SolrDisMaxQuery::setTrigramPhraseSlop() is a PHP method used in the Solr PHP library to set the proximity slop for trigram phrases in a Solr query.

In Solr, a trigram phrase refers to a phrase with three consecutive terms. The proximity slop determines the maximum number of positions between the terms in the phrase. If the terms in the phrase appear within the specified slop, they will be considered a match.

This method can be useful in scenarios where you want to allow some flexibility in matching trigram phrases. For example, if you set the slop to 1, it means that the terms in the phrase can appear in the exact order or with one term in between them.

To use this method, you can provide the desired proximity slop as an argument when calling the method. For example:

php
$query->setTrigramPhraseSlop(1);


This will set the proximity slop for trigram phrases to 1 for the Solr query represented by the $query object.

By setting the proximity slop, you can control the precision and flexibility of trigram phrase matches in your Solr queries.
