Search Ranking determines the ranking of individual document in the results. The top scored document or article will be first in the results shown to the user. Every document indexed will have the data(value) inside fields(keys). When user enters search query, Expertrec finds the documents based on the matching query terms inside documents. You can control the search results by modifying matching logic or defining boost etc. Expertrec supports fine tuning of search results based on below features:
- search weights
- synonyms
- Boost fields
- Filter fields
- search highlighting
1. Search Weights:
Every document has field and associated data inside that field as key/value pairs. When user enters search query, by default all the fields are considered and scores are calculated by Expertrec’s algorithm and then top results are given. You can define the order of match by adjusting weights in your controlpanel. Read More explains this in detail.
2. Synonyms
