Help with BrowseHit getField

[Ariel Valentin]

Hello!

I want to figure out a way to efficiently return field values for all matching BrowseHits. I do not want to use the stored values because in the past we have run into considerable issues with I/O. Based on reading the documentation and reading through the source code, it appears that the FieldValues are set by FacetHandlers. I have tried using SimpleFacetHandler however when I do so the search time slows down considerably (from 464ms to 8000ms on average). 

That makes me feel like I am missing something. Is there an easier/faster way to do this?

Hi Ariel:

     This does not sound right. Returning value from facethandler should be very fast. Would you mind paste your code so we help?

John,

Thanks for your help. I created a Gist that contains the relevant part of the search code here: https://gist.github.com/arielvalentin/d737007c29fa60e7f07f

1. We construct a BrowseRequest that contains relevant user requested information
2. We then create a Browser using an indexReader
• BoboBrowser(BoboIndexReader.getInstance(indexReader));
• browser.setFacetHandler(new SimpleFacetHandler(DocumentField.Guid.getFieldName()));
3. Lastly we convert the BrowseResult into our own SearchResult type

One thing I noticed after we reviewed this code is that I do not close the BoboBrowser so I am going to add that today and see what happens.

Ah, the problem is clear, you are creating a BoboIndexReader from the line 37: browser = new BoboBrowser(BoboIndexReader.getInstance(indexReader));

per request. That is very expensive.

You should keep an instance of BoboIndexReader around for all search request.

Let me know if this works better for you.

I better get on that then.
