I've been working on benchmarking our solr response times in relation to the a variable number of concurrent queries. With maxThreads=150 - I've tried running between 20-100 queries concurrently against our solr instance and have noted that for all n-way (>20) queries I'm finding that performance flatlines at 20-30 requests/second. ...
I'm new to using Solr, and I must be missing something. I didn't touch much in the example schema yet, and I imported some sample data. I also set up LocalSolr, and that seems to be working well. My issue is just with querying Solr in general. I have a document where the "name" field is set to "tom." I keep looking at the config fil...

Any demo/sample project on this to refer to? definitely Jira would be a good example but its source code is not available. I want to know how to ma...
I am writing a wrapper around Zend's lucene implementation and wanted to add a function rebuildIndex() which reads all relevant fields from the database and re-creates the index file in a temporary folder. When the operation is finished, I want to replace the original folder with the new one. How can I lock the original lucene folder whi...
When I do search for the words like Ballantine's, the index gives me the documents that have "'s" only as few search result. I would like to see only those documents which have the full word Ballantine's as it is in the document. How could I change my Searching query? Changing index is very diificult for me now. As I've already indexed...
Does anyone know of companies offering SaaS full text search? I'm looking for something that uses Lucene, solr, or sphinx on the backend, and provides a REST API for submitting documents to index, and running searches. I could build my own EC2 AMI, but I'd have to configure EBS and other stuff, monitor it, etc. Curious if someone has ...
I have a website which has about 200 to 300 static public pages. I am required to bring about some kind of search functionality on the website which will search all of its public pages. I don't want to use external tools like Google site search, etc. Is there a tool or open source code that will index the content and then display the sea...
I tried this Lucene code example, which worked: http://snippets.dzone.com/posts/show/8965 However changing: Query query = parser.parse("st."); to Query query = parser.parse("t"); returned zero hits. How to write a Lucene query that returns all words containing the letter "t" ? (max nbr of hits to return = 20) ...
I have a database which is readonly (I only have the access to view), but I have to index this database for search. The DAO layer to this table is now using a generic DAO approach with Hibernate+JPA. Is it possible to add hibernate search to this view and store the index in a separate database? I am aware that I may lose the capability ...
Hello, I am working in a project that has a big amount of data in Lucene. We need to show a faceted search and the time requiered for it is unacceptable when trying to simulate it using regular Lucene accesss. I have been reading about Solr, but tutorials are not very clear about this basic point: Is the data stored in the same way usin...

i want to know the string matching algorithms used by Apache Lucene. i have been going through the index file format used by lucene given here. it seems that lucene stores all words occurring in the text as is with their frequency of occurrence in each document. but as far as i know that for efficient string matching it would need to pre...

Hi, does anyone have any experiences using the lucene's spatial search component (lucene 3.0)? I tried a very simple example but could not get the search to return anything, see below for all the codes import java.io.IOException; import org.apache.lucene.analysis.WhitespaceAnalyzer; import org.apache.lucene.document.Document; import o...
I have a question regarding performing a lucene query involving permutation. Say I have two fields: "name" and "keyword" and the user searches for "joes pizza restaurant". I want some part of that search to match the full contents of the "name" field and some part to match the full content of the keyword field. It should match all the...

Basically some times a town name will come through to SOLR as "CAMBRIDGE" and sometime's it will come through as "Cambridge" I wanted to use a filter in Solr to stop the SCREAMING CAPS version of the town name. It seems th...
Hi. I need to exclude duplicates in my database. The problem is that duplicates are not considered exact match but rather similar documents. For this purpose I decided to use FuzzyQuery like follows: var fuzzyQuery = new global::Lucene.Net.Search.FuzzyQuery( new Term("text", queryText), 0.8f, ...
I'm trying to utilize the termFreqs method provided by the Searchable plugin to generate a keyword cloud for the most popular terms found in an indexed domain class. The problem is, I only want to get the term frequencies for a subset of the records in the database. I have the following classes: class Text { String title String cont...
With lucene 2.9.1, INDEX.TOKENIZED is deprecated. The documentation says it is just renamed to ANALYZER, but I don't think the meaning has stayed the same. I have an existing app based on 2.3 and I'm upgrading to 2.9, but the expected behavior seems to have changed. Anyone know any more details about INDEX.TOKENIZER vs INDEX.ANALYZER?...
