: Sorry I should have made the objectives clear. The goal is to reduce the : index size by avoiding TermFrequency stored in the index (in .frq : segment files).
Hmmm... why? you're talking about eliminating a single (compressed) int per term, and yet you want positions which take up a lot more space (at a minimum, even if each term only appears once in a single document, that's already as much space as the frequencies) on anything except a toy index, eliminating freq while keeping positions (if it were possible) is unlikely to even noticably affect the index size. what is the motivation for your objective? If your main motivation is to just "to reduce index size", then perhaps tell us more about your configuration/use cases and maybe we can offer alternative suggestions. http://people.apache.org/~hossman/#xyproblem XY Problem Your question appears to be an "XY Problem" ... that is: you are dealing with "X", you are assuming "Y" will help you, and you are asking about "Y" without giving more details about the "X" so that we can understand the full issue. Perhaps the best solution doesn't involve "Y" at all? See Also: http://www.perlmonks.org/index.pl?node_id=542341 -Hoss
