Re: add word filtering?

No. I'm sorry I didn't convey my question very well. Anyway thanks a lot for the info. What I really meant is, I want to filter out some words like for example, "violence" & "hatred" from the search engine results. Consequently lucene will display some alternative results for the above attempted s

How to write to and read from the same index

I'm using Lucene running on Tomcat to index a large amount of email data and as the indexer runs through the mailbox creating, merging and deleting documents it does lots of searches at the same time to see if the document exists. Actually all my modification operations are done "in batch" every x

Phrase Query query

Hi I'm using PhraseQuery in conjunction with WhiteSpaceAnalyzer but it's giving me slightly unusual results. If I have a text file containing the text (quotes are just for clarity): "Hello this is some text" I don't find any results when I search. But if I put spaces before and after the phras

It works perfect. After installation of 1.9. I've the MatchAllDocsQuery. Thanks! -- View this message in context: http://www.nabble.com/Get-All-Entries-t1348226.html#a3610840 Sent from the Lucene - Java Users forum at Nabble.com. -

RE: Get All Entries

I believe there's a MatchAllDocsQuery class from Lucene 1.9 onwards. You can run this query to get all documents. If you are not using 1.9, to my knowledge, you would have to add a redundant field that would true for all documents and query on that field. Something like Field.Keyword("AllDocsTrue"

Hi all I'm really new to lucene. In fact I just found it when i googled a few days ago. Never thought that java have this kind of excellent library for free. I would like to ask a few questions, which is where to add if we would like to filter certain text from being searched, and filter certain

PhraseQuery with synonyms or having n tokens at the same tokenposition.

Hi, PhraseQuery is not working as I wanted,when indexed with synonyms. ex: I have indexed name: "sony dsc-d cybershot" as following tokens provided token positions. 1: [sony:0->4] 2: [dsc:5->10] 3: [dscd:5->10] 4: [d:5->10] 5: [cybershot:11->20] So "dsc-d" is tokenized into 3 tokens "dsc
