OR'ed boolean queries

[MariLuz Elola]

Hello

    I don´t know exactly how is working PrefixQuery,WildcardQuery,RangeQuery 
and  FuzzyQuery expanding to a series of OR'ed boolean queries.

    For example I have an index with 200.000 registries. Each registry has two 
metadatas, NAMEFILE and AGENCY. If I do the search 
    NAMEFILE:ef* 
    I am getting TooManyClauses error, but if I do the search 
    AGENCY:ef* 
    I am getting correctly the results without any error.

    Both metadatas has 200.000 values, but, in the metadata AGENCY there are 
about 30 diferents values and in the metadata NAMEFILE each registry has an 
unique value.

    Both metadatas have been indexed like Field.Text.

    The same happens with RangeQuery. For example:

    The user select PAGE > 0. Internally it is translated like   
PAGE:{0000000000 TO 2147483647}    (2147483647 This is Integer.MAX_VALUE)
    This returns 130.000 registries with value > 0 without TooManyClauses 
error, but using another numeric metadatas I am getting TooManyClauses error..

    The property maxClauseCount is by default (1024).

    Could anybody tell me how it is working?



    Thanks in advance
