public final class DropIfFlaggedFilterFactory extends TokenFilterFactory
Provides a filter that will drop tokens matching a set of flags. This might be used if you had both custom filters that identify tokens to be removed, but need to run before other filters that want to see the token that will eventually be dropped. Alternately you might have separate flag setting filters and then remove tokens that match a particular combination of those filters.
In Solr this might be configured such as<analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <-- other filters --> <filter class="solr.DropIfFlaggedFilterFactory" dropFlags="9"/> </analyzer>
The above would drop any token that had the first and fourth bit set.- Since:
- 8.8.0
