Re: Lucene index in memcache

Hi Erick & Chris , Thanks for your response. I have done some profiling , and it seems the response is slow when there are long queries(more than 5-6 words per query). The way I have implemented is : I pass in the search query and lucene returns the total number of hits, along with ids . I then fe

multi-term query weighting

I have an index with two different sources of information, one small but of high quality (call it "title"), and one large, but of lower quality (call it "body"). I give boosts to certain documents related to their popularity (this is very similar to what one would do indexing the web). The pr

Reusing Document Objects (was Auto Slop)

If I create a Document object, can I pass it to multiple index writers without harm? Or, does the process of being handed to an Index Writer somehow mutate the state of the Document object, say during tokenizing, that would cause it's re-use with a totally separate index to cause problems ...such

You can always read the current index into a RAMdir, but I really wonder if that will make much of a difference, as your op system should be taking care of this kind of thing for you. How big is your index? What kind of performance are you seeing? What else is running on that box? I'd do some pr

I have managed to download and install Lucene. In addition, I have reached the point at which I am able to generate an index and run a search. The search returns a 'raw' list of the HTML pages in which my search term occurs. . . . chapter17, chapter18, etc. Question: how do I go about manipulat

Re: Auto Slop

Examine your indexes and analyzers. The default slop is 0, which means allow 0 terms between the terms in the phrase. That would be an exact match. A slop of 1 is not the default and would allow a term movement of one position to match the phrase. - Mark Walt Stoneburner wrote: I just ran in
