# Boost Relevance

You can boost the percentage relevance that IDOL Server gives to query results by using the following methods:

- Use a field process. You can set up a field process in the IDOL Server configuration file to boost the percentage relevance of query results according to the number of times terms in specified fields match the query terms.

- Use BIAS. You can use the `BIAS` field specifier at query time to boost the percentage relevance of query results according to the numerical proximity of a specified field to a particular value.

- Use multipliers. You can multiply the weight of individual query terms to boost the relevance of results that match these terms accordingly.

- Use the AutnRankType field. You can create a field in documents that indicates their importance and instruct IDOL Server to take the value of this field into account when it calculates the relevance that the document is given if it returns as a result.
