Subject Re: Query filters/analyzers
Date Thu, 01 Oct 2009 11:34:20 GMT
Hi Claudio,

in schema.xml, the <analyzer> element accepts the attribute type.
If you need different analyzer chains during indexing and querying, 
configure it like this:

<fieldType name="channel_name" class="solr.TextField">
	<analyzer type="index">
	<!-- indexing analyzer chain defined here -->
	<analyzer type="query">
	<!-- query analyzer chain defined here -->

If there is no difference, just remove one analyzer element and the type 
attribute from the remaining one.

You can check after indexing in the schema browser (admin web frontend) 
what analyzer chain is applied for indexing and querying on a certain field.

When you have detected the input language, simply choose the correct 
field, and the configured analyzer chain for that field will be applied 

E.g. input is italian:

text-it has the italian analyzers configured for index and query, so to 
the input, the italian analyzers will also be applied.
