Hi,
I am fairly new to Lucene and is now currently going through its source
code. I am currently trying to determine how Lucene calculate the frequency
of a term in each document located.
I encounter a method named readVInt() in IndexInput class. It seems
everytime it called this method it will
and variable length manner.

The frequency is tracked at index time. It's simply a read at query

Hi,
I am currently using Lucene to build a search engine and is trying to

that calculate the score and return the results.

I thought maybe I can
store some extra value into the .frq file then I will have no need to
continuously use the reader. Anyone can provide other suggestion? Thanks

Hi,
I am currently working on retrieving url and contentLength of each document
found during the search. I want to retrieve it during the calculation of
score so that I can influence the score in some other way.
I used the methods from TermDocs and TermEnum to get the information.
However, the u

Hi,
I want to use a Reader to read a document everytime a matching document is
found during search time. So basically, everytime during the calculation of
the score for a document, I will use the reader and retrieve some
information from the index. Will this lower the searching performance?
