Text Filter Parameter


The syntax for the text filter parameter is:


A query string may contain many s.fq parameters. There are no defaults for the s.fq parameter. Lucene escaping applies to this parameter. Characters that may need to be escaped include: +-&amp;|!(){}[]^"~*?:\. Special characters only need to be escaped if their special meaning was not intended.


The text filter parameter is used to apply reusable text filters to queries. Unlike text queries, text filters do not affect document relevance score. Text filters are useful when a facet value filter is not available to narrow the search, and multiple queries need to be run inside the same limiting scope, without the limiting scope affecting relevance scores.
