Hi everybody, I would like to know your suggestions to calculate Term Frequency in a Lucene document. Currently I am using MultiFields.getTermDocsEnum, iterating through the DocsEnum 'de' returned and getting the frequency with de.freq() for the desired document.
My solution gives me the result I want but I am having time issues. For instance, I want to calculate the term frequency for a given term for N documents in a sequence. Then, every time I have a new document I have to retrieve exactly the same DocsEnum again and iterate until find the document I want. Of course I cannot cache DocsEnum (yes, I did this huge mistake) because it is an iterator. Do you have any suggestions on how I can get Term Frequency in a fast way? The unique suggestion I had up to now was "Do it programatically, don't use Lucene". Should be this the solution? Thank you. Regards, Bianca Pereira
