Yes, using fieldType, you can have Solr run the PatternReplaceFilter for you.
So, for example, you can declare something like this: ---------- <fieldType name="simpleText" class="solr.TextField" > ... </fieldType> <fieldType name="strippedText" class="solr.TextField" > ... Put the PatternReplaceFilter in here. At least for indexing, maybe for query as well </fieldType> ... <field name="description" type="simpleText" stored="true" indexed="true"/> <field name="suggestion" type="strippedText" stored="true" indexed="true"/> ... <copyField source="description" destination="description"/> ----------- I would suggest doing this in your schema, then starting up Solr and using the analysis admin page to see if it will index and search the way you want. That way you don't have to pay the cost of actually indexing the data to find out. -Todd -----Original Message----- From: Aleksey Gogolev [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 22, 2008 9:24 AM To: Feak, Todd Subject: Re[2]: Question about copyField Thanks for reply. I want to make your point more exact, cause I'm not sure that I correctly understood you :) As far as I know (correct me please, if I wrong) type defines the way in which the field is indexed and queried. But I don't want to index or query "suggestion" field in different way, I want "suggestion" field store different value (like in example I wrote in first mail). So you are saying that I can tell to slor (using filedType) how solr should process string before saving it? Yes?
