Filters are cached in an LRU Cache keyed on the contained query or filter object. Using this will speed up overall performance for repeated uses of the same expensive query/filter. The sorts of queries/filters likely to benefit from caching need not necessarily be complex - e.g. simple TermQuerys with a large DF (document frequency) can be expensive on large indexes. A good example of this might be a term query on a field with only 2 possible values - "true" or "false". In a large index, querying or filtering on this field requires reading millions of document ids from disk which can more usefully be cached as a filter bitset.

For Queries/Filters to be cached and reused the object must implement hashcode and equals methods correctly so that duplicate queries/filters can be detected in the cache.

The CoreParser.maxNumCachedFilters property can be used to control the size of the LRU Cache established during the construction of CoreParser instances.

Creates a NumericRangeFilter. The table below specifies the required attributes and the defaults if optional attributes are omitted. For more detail on what each of the attributes actually do, consult the documentation for NumericRangeFilter:

If an error occurs parsing the supplied lowerTerm or upperTerm into the numeric type specified by type, then the error will be silently ignored and the resulting filter will not match any documents.

Creates a NumericRangeQuery. The table below specifies the required attributes and the defaults if optional attributes are omitted. For more detail on what each of the attributes actually do, consult the documentation for NumericRangeQuery:

A ParserException will be thrown if an error occurs parsing the supplied lowerTerm or upperTerm into the numeric type specified by type.

Builds a BooleanQuery from all of the terms found in the XML element using the choice of analyzer

UserInputQueryBuilder uses 1 of 2 strategies for thread-safe parsing: 1) Synchronizing access to "Parse" calls on a previously supplied QueryParser or.. 2) creating a new QueryParser object for each parse request
