INDICA provides the relevance level of matching documents based on the terms found. To boost a term use the caret, "^", symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be.
Boosting allows you to control the relevance of a document by boosting its term. For example, if you are searching for
jakarta apache
and you want the term "jakarta" to be more relevant boost it using the ^ symbol along with the boost factor next to the term. You would type:
jakarta^4 apache
This will make documents with the term jakarta appear more relevant. You can also boost Phrase Terms as in the example:
"jakarta apache"^4 "Indica search"
By default, the boost factor for each term or phrase is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)
