Subject Many keywords problem
Date Sun, 06 May 2012 13:57:34 GMT
       I met a problem about how to search many keywords  in about 5,000,000 documents.For
example the query may be like "(a1 or a2 or a3 ....a200) and (b1 or b2 or b3 or b4 ..... b400)",I
found it will take vey long time(40seconds) to get the the answer in only one field(Title
field),and JVM will throw OutMemory error in more fields(title field plus content field).Any
suggestions or good idea to solve this problem?thanks in advance.
