Hi: There are types of TermQuery,TermRangeQuery,and the BooleanQuery and etc built in lucene,and they can be combined to make a powerful search.
However I wonder if this is useful for a user in the client side? For example,I build a web user interface with a search textfield(like the google) for inputting,when user enter something to the textfield,I got it and do the searching. Now is that mean I should do something to the string from user? Suppose user enter "lucene document" for searching, then I can change them to "lucene AND document" or "lucene OR document" or "+lucene-document" or .... and something else. But the problem is that how did I know the intention of the user? BTW,In my opinion there is always a contradiction between the *quantity* and *quality* of the search result. That's to say if I want the search result as precise as possible I should use the "Lucene AND document" instead of the user entered string,however if there is no precise result,it seems that I should use the "lucene or document"(just return something to user). So I am confused how to handle these problem. PS: Maybe this topic is not very a lucene question,but it is search related, and you guys are experter of searching,so I asked for help. :)
