Site Search

Everything you need to know about site search

What is a Site Search for a website?

Anyone who has ever been to a store and found themselves confused about where to find the product they are looking for understands the significance of a well-versed salesman to guide them.

Very similarly, every customer for an online website store is aware of the significance of an internal site search. The site search is a custom-made search engine for a particular website and responds to user queries by accessing the website catalogs. 

This feature on a website helps the users to directly type and search the product they need without having to browse the whole website.

How does search work on a website?

site search architecture

 

A high level of engineering expertise goes into making a site search effective and relevant.
Let’s understand the steps one by one.

1. Crawler:

site search crawler

It acts as an input tool by connecting the search engine query to new pages. Also, handles large pages while maintaining the significance of the pages since when they were last visited by the crawler as they are subject to change.


The crawler may cater to a single site or many different pages depending on the design.
For enterprise searches, the crawler must be designed to be efficient to access both the internal company document links and external links from personal and corporate directories to account for resources (emails, PDFs, database records, etc.) along with other needed company information.

2. Conversion:

Crawler found documents from a link are not likely plain text or in the format required. They may be in other forms (HTML, PowerPoint, etc.).

This data is converted in the form of consistent text plus metadata through a conversion tool.

For HTML/XML, it is mostly text transformation component.However, for other formats like PDF or Microsoft Office documents, it is the first step before further processing. 

Some problems are encountered due to the encoding of the texts in the documents. Most of the world’s languages are coded by Unicode which uses 16 bits to process the documents.

3. Document Data Store: 

document data store

The document datastore is the huge database on the site managing a large number of company documents and structured data.

It contains document metadata, information taken from various documents, links, and the text associated with the links called ‘Anchor text’.

Mostly, the simpler version is used by most websites to reduce the retrieval times.

4. Text Transformation:

  • Parsing- Processes the text tokens in the document while recognizing the structural elements like links, headings, titles, etc. The first step requires tokenizing the document and the query to compare. The tokens are alphanumeric characters with spaces.
  • Stop Words- Simple terms posing as index terms, called stop words should be removed.
    Examples may be, “of”, “for” “to”. These help in sentence formation but have no contribution to sentence meaning. Even if removed, they do not alter search results.

  • Stemming- words derived from a common stem are grouped in the process of stemming increasing the probability of the words in documents and queries matching each other. It should be done carefully to avoid search problems.

  • Link Extraction and Analysis- this separates the text and stores it in the document data store while parsing to identify the links and the anchor text.
  • Information Extraction- is done for the identification of index terms that are more complex than single terms and need special computation tactics. There is special emphasis on semantic content analysis like named entity organizers which can identify specific content (Company name, Person name, etc.)
  • Classifier- Identifies the class-related metadata in documents or the part of documents. The documents are assigned with pre-decided labels(“business” or “household”). There may be other types of classification including identification of spam and advertising-related content to help rank the data.

5. Index Creation:

  • Document Statistics- Carries out the simple task to bring together statistical information about words, features, and documents. The ranking component uses this information to compute the scores for the gathered documents.
    All of this is determined by the retrieval model and associate ranking algorithm. These are stored in lookup tables for faster retrieval.

  • Weighting- Index words, and their occurrences in the document become very important during ranking. The weighting component uses the statistics in the document to calculate the weight and then stores them in the lookup tables, improving the efficiency of the query process.
  • Inversion- It is the core of indexing. It changes the document-term information stream which is derived from the text transformation component into a term document information to create inverted indexes, processing queries faster increasing the efficiency.
  • Index Distribution- distributes the indexes created to multiple computers and multiple sites on a network potentially for efficient performance allowing parallel processing of indexing and queries.

6. User Interaction:

  • Query input- It provides for interface and parser regarding query language. This can be the addition of quotes as an example which tells the system that the quoted words should occur in a phrase not individually.
  • Query Transformation- Improves the initial query using a range of techniques before and after the document is ranked. Tokenizing, stopping, and stemming are the simpler ones while the most advanced ones include spell checking and query suggestions. Helps in suggesting alternatives to the query or adding terms making the query more meaningful.
  • Results Output – Displays the ranked content taken from the ranking component. 

7. Ranking:

  • Scoring- uses the ranking algorithm to score the documents based on the retrieval model.
  • Performance Optimization- Helps decide the best ranking algorithm and indexes to decrease the response time and increase the query output.
  • Distribution- Ranking can be distributed in the same manner as the index, this is decided by the query broker to allot queries to the specific processors in the network creating the final list of ranks for the query. Caching is an example where indexes and sometimes ranked documents are kept in the local memory for faster processing and retrieval.

8. Evaluation:

  • Logging- Tracking all the user queries is beneficial to keep a track of query suggestions, spell checks, and several other tasks to improve search effectiveness in the long run.
  • Ranking analysis- Evaluation measures are used to measure the outcomes that are useful for the application. Many search queries require quality from the top-ranked documents, not the whole list.
  • Performance Analysis- Response time and throughput are some of the measures used in calculating the performance, can also be tested using simulations that replace human input with mathematical models.

    Why does my website need a Search bar?

    A highly efficient website converts visitors into customers. Spending a lot of time searching for their product, users lose interest.

    When there are hundreds of pages related to different products on your website, a specifically curated search engine is needed as all the products cannot be listed on the home page due to limited space.

    The search engine queries made also help to keep logs of the most popular products for proper algorithm training.

    Site Search also efficiently reduces the bounce rates for your website creating a positive effect on your website SEO.

    An optimized site search on your website also helps in getting the site links search box in Google search results, increasing your organic website traffic.

    What is the difference between site search and navigation?

    Site search works on the idea that the user already knows what they are looking for and hence can directly type a keyword to locate the product on the website.

    Navigation, on the other hand, offers the user a list of different categories of products on their website catering to likely users, looking to explore the website with no particular product in mind.

    Alternatives to Google Site Search

    Google Site Search started as an easy and ad-free option for websites to add search functions to their websites for a monthly fee. This was discontinued in 2017, introducing Google Custom Search Engine.

    Its cons in the form of extra cost to block ads placed by Google AdSense are detrimental to the company’s image in ownership of the website.

    There are alternatives to Google Site Search that help company websites have more control over the advertisement displays as well as the search results. These can be on-premise platforms as well as SaaS solutions with cloud hosting.

    SaaS search solutions are the easiest of the lot and offer APIs to dictate search result displays on the website, indexing the content on the site and delivering search results automatically. Search infrastructure, abilities to run on multiple channels like mobile or web and also in different languages are beneficial.

    Some providers in this range are Expertrec, SiteSearch 360, Swiftype and Algolia, Cludo, and Klevu for E-commerce. 

    Cloud Providers provide custom site search solutions with services hosted in the cloud. It can be a bit difficult to index to make the new fields appear in the search.

    The big players in this space are CloudSearch(Amazon) and Azure Search (Microsoft).

    Examples are WordPress, Joomla, HubSpot with built-in functions for site search.

    Internal Search Solutions on E-commerce Platforms
    They do not require any hassle of installations as well as have no extra costs but they are not as highly efficient as a standalone solution custom-built for a website.
    For example, Magento, Shopify, etc.
