Re: Getting terms from unstored fields, doc-wise

Hi If the data is not stored then it cannot be retrieved in the same format. Using IndexReader as you listed you could retrieve the list of the terms available in the doc. It may be analyzed. You may not be getting exact data. Regards Aditya www.findbestopensource.com On Fri, Jul 27, 2012 at 1:3

Re: Getting terms from unstored fields, doc-wise

Thanks for the reply Abdul. I was exploring the API and I think we can retrieve all those words by using a brute-force approach. 1) Get all the terms using indexReader.terms() 2) Process the term only if it belongs to the target field. 3) Get all the docs using indexReader.termDocs(term); 4) S

Lucene vs SQL.

If I want to set up a database that is totally flat with no joins, is there any reason not to use lucene. The reasons I would be curious about are things like insert performance and whether there are any queries that either don't work in lucene or perform better in MySQL/postgres. -

Getting terms from unstored fields, doc-wise

Hi, I've an index to analyze (manually). Unfortunately, I cannot rebuild the index. Some of the fields are 'unstored'. I was wondering whether there's any way to get the terms from an unstored field for each doc. Positional information is not necessary. Lucene version is 3.5. The reason am tr

Facet Support

Hi Team, I would like to know if Lucene 4.0 will support facetted search. Thanks in advance. Best regards, Ranjith... [cid:image001.gif@01CD6B26.B4C4D460]Ranjith Ratna Kumar S / Capgemini India / Bangalore Warner Bros. | Techni

Aligning text analyses, with and without stopwords

Hello, I want to align the output of two different analysis pipelines, but I don't know how. We are using Lucene for text analysis. First, every input text is normalized using StandardTokenizer, StandardFilter and LowerCaseFilter. This yields a list of tokens (list1). Second, the same input text is

Re: QueryParser and BooleanQuery

Hi Trejkaz, I am using the Standard Analyzer for my indexing. Can you provide an example with which I can use the BooleanQuery to add both the fields in the same forms and yet the documents are searched? I would be really grateful if you can provide example for parsing the text as well which is p

Re: Question on ElisionFilter with d'

Hi, Sorry I forgot the most important : i use lucene 3.6. Here is my code : tokenStream = new ElisionFilter(Version.LUCENE_36, tokenStream); I looked at the source code of ElisionFilter, and DEFAULT_ARTICLES doesn't contain "d" and "c", in order to manage terms like /"d'une/" or "/c'est"/.
