Solr: Remove Double Quote Characters from a Field

Question

Some of our documents have double quote characters in them and that can break some searches on those documents. How do I set up the PatternReplaceCharFilterFactory to remove double quote characters? I tried various escape characters but to no avail, eg:

<charFilter class="solr.PatternReplaceCharFilterFactory" pattern="[;:\\'\\"\\\\*/\\),\\(\\-]" replacement=" "/>

Does not appear to work as the core won't load with a schema parsing error.

Answer 1

显然，由于schema.xml是XML，因此我需要使用特殊的XML令牌"
