Error from Lucen.Net >> BufferedIndexInput.cs

I got the portal installed on my desktop yesterday and play with, everying was working fine yesterday. now when I come back and play with it again, I got error on every page after I posted any thing.

The error below I got it after I posted a reply to a message in the forum.

So, how can I fix this or remove the Lucen.Net from the portal because this Indexing engine does impact the portal performance and it does not really give much benefit, I mean the search functionality does not give accurate result.

read past EOF

Re: Error from Lucen.Net >> BufferedIndexInput.cs

I'm not sure what happened but you can delete the index files for lucene and it will re-build the index on the next search.

The index files will be in ~/Data/Sites/[SiteID]/index
SiteID is likely 1
Delete all files from this index folder then do a search for something in the site and it may solve the error.

Hope it helps,

Joe

Re: Error from Lucen.Net >> BufferedIndexInput.cs

Ok, I will try it when I get a chance. In the mean time, can you explain how the Lucen work? is it like the class get called everytime there is a new thread posted, a new HTML content added or updated? or it works in the background in HttpHandler. I think I like to remove it from the portal since I worry about performance and I don't need that feature.

Thank you for all your hardwork.

Re: Error from Lucen.Net >> BufferedIndexInput.cs

Yes, every time content is added or forum posts are made, entries are written to the lucene index so that the new or updated content can be searched. The task to index the content is queued on a new thread so it doesn't impact the user perception of performance.

Currently there is no way to disable it but it would not be hard to add a web.config setting to disable it and go through the code and add a check to this variable where needed. Maybe we can do that in a future version, no-one has ever asked to be able to disable it. I doubt very many people want to disable it, especially for forums.
