search for: document_ids

Hi All I have made my xapian indexer automatically create new indexes once it reaches X documents in each, and for each document that I add to each sub-index, I record its document_id and its index_id (relating to what index the document ended up in). writabledatabase_add_document() returns document_id:s beginning from 0 for each new index when you add new documents, like you would expect. So

OK, I'm indexing my data with the scriptindex. I want to be able to restrict the search by the category field. Do I need to do anything to the data itself? Like, literally prefix it with the characters "XC"? Below is my indexor for scriptindex and the my php code... document_id : field=ref unique=Q boolean=Q search_id : field=document_id index=S document_title : field=title

Hi all Is there a way to do adaptive query scoring (as in popular results returned by a query should get more weight because they are getting clicked more often) in xapian? Is this what the rset class should be used for? I could write a php app to do adaptive results scoring for separate words (just recording the clicks and then have a cron:ned script add weight to the document_id:s for the

Hi guys I have implemented xapian on a website, and it currently has about 2M items in its index. Its all been working quite nicely so far, until I tried removing some old items from the index (removing items when the index was smaller was no problems at all).

I need to give users the ability to optionally add metadata to documents. Another way to state this is the fact that users need to add at least 5 categories to a document. Basically what I want to do is dynamically add metadata (or categories) to a document on an ad hoc basis. Here are the options that I have thought of: **Option 1:** Should I do this by dynamically creating new table columns in

So I''m not even sure if I''ll be able to properly explain what I''m trying to do, but I''ll do my best. Let''s say that I have two models: Document and Option. A Document has many Options (and, by extension, an Option belongs to a Document). Each document may have a different number of options, hence why I made it a separate model. Each document has the

I am looking to have a number of categories populated from my results of a search. For example, searching on "sport" would display all results for sport. I want to also have a number of categories to refine the documents down. So by clicking on the "Fishing" category or the "Shooting" category, I would only see the results on sport around that category. Now for

Hi, The following code, from Angelo Canty article on line "Resampling Methods in R: the boot Package, 2002", works fine for Angelo Canty using R 2.6.0 on Windows XP. It also works for me using R 1.2.1 and S-PLUS 2000 on Windows XP after installing the S-PLUS bootstrap library, with slight differences in my outputs. > library(boot) > library(survival) >
