Re: Adding fields with same field type complains that they have different term vector settings

Hi Albert, Unfortunately, you have fallen into a common and sneaky Lucene trap. The problem happens because you loaded a Document from the index's stored fields (the one you previously indexed) and then tried to modify that one and re-index. Lucene does not guarantee that this will work, because

Adding fields with same field type complains that they have different term vector settings

Hi, I'm upgrading a project to lucene 8.5.2 which had been using 3.0.0. Some tests are failing with a strange issue. The gist of it is, we create fields that need position and offset information. Inserting one field works ok, but then searching for the document and adding another value for the

Are term vector position returned ordered in Lucene 3.6?

Hi, I am extracting term vectors position in Lucene 3.6. First I extract the term vector and get the indexes from the "indexOf" method as suggested for extracting the position. TermPositionVector termFreqVector = (TermPositionVector) reader.getTermFreqVector(i, termField); Stri

Re: Term vector Lucene 4.2

Hi Andi, Here is how you could retrieve positions from your document: Terms termVector = indexReader.getTermVector(docId, fieldName); TermsEnum reuse = null; TermsEnum iterator = termVector.iterator(reuse); BytesRef ref = null; DocsAndPositionsEnum docsAndPositions = null;

Term vector Lucene 4.2

Hi, I have a problem while trying to extract term vector's attributes (i.e. position of the terms). What I have done was: Terms termVector = indexReader.getTermVector(docId, fieldName); TermsEnum reuse = null; TermsEnum iterator = termVector.iterator(reuse); PositionIncr

Index a manually constructed term vector as a Lucene document

Hi, I have some term vectors each with a number of (term, score) pairs. These vectors were derived from text documents which are no longer obtainable. I want to be able to add these vectors as individual documents to Lucene index. I understand this can be accomplished by writing my own analyzer c

Re: term vector - WITH_POSITIONS_OFFSETS vs YES in terms of search performance

The performance impact should only be at indexing time, unless you actually retrieve the vectors for some number of hits at search time. Mike On Tue, Nov 30, 2010 at 2:28 PM, Maricris Villareal wrote: > Hi, > > Could someone tell me the effect (if any) of having term vectors set to > WITH_POSITI

term vector - WITH_POSITIONS_OFFSETS vs YES in terms of search performance

Hi, Could someone tell me the effect (if any) of having term vectors set to WITH_POSITIONS_OFFSETS vs YES in terms of search performance? I did some testing and the results were inconclusive. In one case, WITH_POSITIONS_OFFSETS was searched faster than YES, in all others, it was the reverse. Is

Hi folks: I need to know how to get the frequency term vector of a field from a remote index in another host. I know that *IndexSearcher *class has a method named *getIndexReader().getTermFreqVector(idDoc, fieldName) *to know the the term frequency vector of certain field* *but I am using

Hi all, Can a vector of terms be contructed in Lucene. A term vector for a document, for example, would contain the indexed terms of that document. Also, is it possible to get a handle to the actual term-document matrix. Thanks in advance, Srikanth
