: I want to perform a search for documents that contain the word starting with : given KEYWORD or Ending with given KEYWORD. : : Ex: Say document contains "RenjiMathewThomas" : : Now I want to perform a search for all the documents that contain the word : starting with "Renji" : or a search that for document that contain the word ending with "Thomas"
the WordDelimiterFilter can help you with this specific case ... because it knows to tokenize (ie: split) works on case change boundaries ... but if you want to solve the more general case (ie: search for "enji" and match that input) you'll need to go with more generic wildcard still tricks ... i would recommend something like an NGram approach to efficiently match on the "suffix" style queries (as well as the more easily supported prefix queries) -Hoss
