Hello all, Currently we are using edismax query parser in an internal application, we've detected that some wildcard queries including "*" are causing some performance issues and for this particular case we're not interested in allowing any user to request all the indexed documents.
This could be easily escaped in the application level, but right now we have several applications (using several programming languages) consuming from Solr, and adding this into each application is kind of exhausting, so I'm wondering if there is some configuration that allow us to treat this special characters as normal alphanumeric characters. I've tried one solution that worked before, involving the WordDelimiterFilter an the types attribute: <filter class="solr.WordDelimiterFilterFactory" generateWordParts="0" generateNumberParts="0" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="0" preserveOriginal="0" types="characters.txt" /> and in characters.txt I've mapped the special characters into ALPHA: + => ALPHA * => ALPHA Any thoughts on this? --------------------------------------------------- XII Aniversario de la creación de la Universidad de las Ciencias Informáticas. 12 años de historia junto a Fidel. 12 de diciembre de 2014.
