Lucene example source code file (README.txt)

This example Lucene source code file (README.txt) is included in the DevDaily.com "Java Source Code Warehouse" project. The intent of this project is to help you "Learn Java by Example" TM.

The Lucene README.txt source code

This module contains a number of filter and query objects that add to core lucene.

==== The "MoreLikeThis" class from the "similarity" module has been copied into here.
If people are generally happy with this move then the similarity module can be deleted, or at least a 
"Moved to queries module..." note left in its place.

==== FuzzyLikeThis - mixes the behaviour of FuzzyQuery and MoreLikeThis but with special consideration
of fuzzy scoring factors. This generally produces good results for queries where users may provide details in a number of 
fields and have no knowledge of boolean query syntax and also want a degree of fuzzy matching. The query is fast because, like
MoreLikeThis, it optimizes the query to only the most distinguishing terms.

==== BoostingQuery - effectively demotes search results that match a given query. 
Unlike the "NOT" clause, this still selects documents that contain undesirable terms, 
but reduces the overall score of docs containing these terms.

==== TermsFilter -  Unlike a RangeFilter this can be used for filtering on multiple terms that are not necessarily in 
a sequence. An example might be a collection of primary keys from a database query result or perhaps 
a choice of "category" labels picked by the end user.

==== RegexQuery - Implements the regular expression term search query.
