Re: implementing our own Scorer (BM25)

Excuse me, I don't want to write a very long email. This is the BM25 Scorer formule: log((N-f+0.5)/(f+0.5)) · (k1 + 1) · c / (c+k1·( (1-b)+b·l/L)) where N = total number of documents f = inverse frecuency (number of documents which contain the term)

Don't use the same index for updating and searching

Hi, I posted a while ago about sudden FileNotFoundExceptions. In a nutshell: my Lucene index went corrupt after a couple of days under heavy load on a Linux server with missing segment files. The problem kept occuring, but I haven't found the cause. I couldn't reproduce it with a simulated load o

What is the use case you're trying to solve? It doesn't make sense to me that you want to take a query from a user and split it over fields under the covers. Why not just index those separate fields into the yet a third field and search there? Or why not just put it all into one field in the fir
