EDIT: Solved with a hack for now. Added at line 473: if (isset($this->_termsFreqs[$termId][$docId])) { } This happens only when I'm searching for multiple words, e.g.: +word1 +word2 + word3 I get this massive error: Notice: Undefined offset: 2 in C:\wamp\www\project\library\Zend\Search\Lucene\Search\Query\MultiTerm.php on line...
When implementing Zend Lucene, do we need to install Java on our server or not? ...
I'm trying to decide on an open source search/indexing technology for a .Net project. It seems like the standard out there for Java projects is Lucene, but as far as .Net is concerned, the Lucene.Net project seems to be pretty inactive. Is this still the best option out there? Or are there other viable alternatives? ...
I have a problem creating an index with Zend_Search_Lucene. Now, everything works fine on my local machine so I guess there is just an issue with file permissions on the webserver. Here is how I'm trying to create index in controller: $index = Zend_Search_Lucene::create('/data/users_index'); Of course the data directory has permissi...

Say my requirement is "search for all users by name, who are over 18" If i were using SQL, i might write something like: Select * from [Users] Where ([firstname] like '%' + @searchTerm + '%' OR [lastname] like '%' + @searchTerm + '%') AND [age] >= 18 However, im having difficulty translating this into lucene.net. This ...

When a keyword is entered, I want to display a link to all the PDF articles where the keyword appears, and also all the music files and video files which are tagged with the keyword in question.

I'm looking for a stand-alone full-text search server with the following properties: Must operate as a stand-alone server that can serve search requests from multiple clients Must be able to do "bulk indexing" by indexing the result of an SQL query: say "SELECT id, text_to_index FROM documents;" Must be free software and must run on Li...
I have two separate indexes holding different fields that together contain all the searchable fields for an index. For example the first index holds the indexed text for all documents, and the second holds tags for each and every document. Note the example below is a bit wonky as I've changed the names of the entities. Index1: text ...
Hi all, I am testing Lucene.NET for our searching requirements, and I've got couple of questions. We have documents in XML format. Every document contains multi-language text. The number of languages and the languages itself vary from document to document. See example below: <document>This is a sample document, which is describing a <...
Is there a way of keeping the index in RAM instead of keeping it on the hard disk? We want to make searching faster. ...
In lucene, I can do the following doc.GetField("mycustomfield").StringValue(); This retrieves the value of a column in an index's document. My question, for the same 'doc', is there a way to get the Doc. Id ? Luke displays it hence there must be a way to figure this out. I need it to delete documents on updates. I scoured the docs b...
I can't find a straightforward yes or no answer to this! I know I can send multiple reads in parallel but can I query an index while a seperate process/thread is updating it? ...
Hi, iam trying to implement an Searchmachine into my site. Iam using Zend_Search_Lucene for this. The index is created like this : public function create($config, $create = true) { $this->_config = $config; // create a new index if ($create) { Zend_Search_Lucene_Analysis_Analyzer::setDefault( new Zend_...
I've built a Lucene Directory implementation for jdbm, an embedded Java database. Part of the Directory API are two methods related to "file" modification dates: touchFile and fileModified (javadoc). My question is, what is the purpose of these methods? I've searched the entire Lucene core source tree, and found no usage of these meth...
How can I do a Filter across multiple fields in Lucene.Net? On one field I simply do: TermQuery tool = new TermQuery(new Term("Tool", "Nail")); Filter f = new QueryFilter(tool); If I now wanted to add a nail length to the filter, how can I do that? Also, I want the user to be a able to do a search with no search term (i.e. by just c...
We have a database of movies and series, and as the data comes from many sources of varying reliability, we'd like to be able to do fuzzy string matching on the titles of episodes. We are using Solr for search in our application, but the default matching mechanisms operate on word levels, which is not good enough for short strings, like ...
With Lucene, what would be the recommended approach for locating matches in search results? More specifically, suppose index documents have a field "fullText" which stores the plain-text content of some document. Furthermore, assume that for one of these documents the content is "The quick brown fox jumps over the lazy dog". Next a sear...
Hi, I am using Lucene in my portal (J2EE based) for indexing and search services. The problem is about the keywords of Lucene. When you use one of them in the search query, you'll get an error. For example: searchTerms = "ik OR jij" This works fine, because it will search for "ik" or "jij" searchTerms = "ik AND jij" This works fi...
