I have an MS SQL database and have a varchar field that I would like to do queries like where name like '%searchTerm%'. But right now it is too slow, even with sql enterprise's full text indexing. Can someone explain how Lucene .Net might help my situation? How does the indexer work? How do queries work? What is done for me, and ...
If anyone has done this, please let me know. I don't know anything about lucene.net. I have never used it, but I heard about it. I was wondering how something like that would integrate with the Linq entity framework? ...
According to this post on how to do query auto-completionsuggestions in lucene getting "Did You Mean" functionality best involves using a LuceneDictionary. But I probably would have used a fuzzy query for this before reading this post. Now I'm wondering which is faster, which is easier to implement? ...
I'm trying to add the lucene sandbox contribution called term-highlighter to my pom.xml. I'm not really that familiar with Maven, but the code has a pom.xml.template which seems to imply if I add a dependency that looks like: <dependency> <groupId>org.apache.lucene</groupId> <artifactId>lucene-highlighter</artifactId> </dependency>...
I use Lucene.Net to index some documents. I want to show the user a couple of lines as to why that document is in the result set. just like when you use google to search and it shows the link and followed by the link there are a few lines with the keywords highlighted. any ideas? ...
I need lucene to search for synonyms as well as the actual keyword. that is if I search for "CI", I want it to search for CI OR "continues integration". at the moment I search for keywords I have the synonyms for and replace them with the "OR-ed" version, but I suspect there should be a better way to do this. my method will not work for ...
When using Lucene.Net with ASP.NET, I can imagine that one web request can trigger an update to the index while another web request is performing a search. Does Lucene.Net have built in it the ability to manage concurrent access, or do I have to manage it, to avoid "being used by another process" errors? EDIT: After reading docs and ...
I'm using Lucene.Net in an ASP.NET application on a shared host. Got this stack trace shown below. What's the work around? [SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] System.Security...
I know its possible to get the top terms within a Lucene Index, but is there a way to get the top terms based on a subset of a Lucene index? I.e. What are the top terms in the Index for documents within a certain date range? ...
I've got nutch and lucene setup to crawl and index some sites and I'd like to use a .net website instead of the JSP site that comes with nutch. Can anyone recommend some solutions? I've seen solutions where there was an app running on the index server which the .Net site used remoting to connect to. Speed is a consideration obviously ...
Am I able to integrate Apache Nutch crawler with the Solr Index server? Edit: One of our devs came up with a solution from these posts Running Nutch and Solr Update for Running Nutch and Solr Answer Yes ...
I'm using Solr and wish to be able to log queries/tokens to a database for analytics for both marketing and suggested search functionality. I'm guessing that a Lucene filter would be a good way of doing this, maybe putting a filter in the query filter chain for a given field type which logs to a specified database. I'm wondering the bes...
Our company has thousands of PDF documents. How do we create a simple search engine using Lucene, Solr or Nutch? We'll provide a basic Java/JSP web page were people can type in words and perform basic and/or queries then show them the document links of all matching PDF's. ...
I'm currently running Lucene.net in a web application and am wondering about the best method, performance-wise. I currently have it set up so that all index writes get processed together in a scheduled process, along with optimizing the index. However for searching - I'm currently opening and closing the searcher per search, which I kn...
Lucene is an excellent search engine, but the .NET version is behind the official Java release (latest stable .NET release is 2.0, but the latest Java Lucene version is 2.4, which has more features). How do you get around this? ...
I'm using Hibernate for a Java-based Web Application and want to add full-text search via Compass. Compass is supposed to support that, but fails to provide any useful Getting Started guide. I could figure out that I have to annotate my Entities with @Searchable and the various @SearchableXXX variations and accessing Compass in my servi...
I'm using Lucene.net, but I am tagging this question for both .NET and Java versions because the API is the same and I'm hoping there are solutions on both platforms. I'm sure other people have addressed this issue, but I haven't been able to find any good discussions or examples. By default, Lucene is very picky about query syntax. ...
Hi, I'm wanting to add a search box onto my website - which is built using Zend Framework 1.6 - using Zend Search Lucene. The majority of my content is static, and held within Controller Views. Does anyone have a script that can index content from the views, and add them into the Lucene search database so I can search them? Many than...
I am running a Solr instance on Jetty and when I search using the Solr admin panel, it returns the entire document. What should I do to get only specified fields from each Solr document returned by the search? ...
I want to use lucene.net to index records in our database. The records are stored in several different tables and tied together through a records table. Would it be better to index each table separately and tie the search results together in code, or should I tie the records together coming out of the database and place them all in one...
