Simple PHP Proxy returns incorrect JSON from Apache Solr instance

I’ve implemented Ben Alman’s simple-proxy.php to communicate to an Apache Solr instance (in this case my local) outside of my domain.

I’ve followed the instructions in full, the core of which is to set the simple-proxy.php on my domain’s file server.

I’m curious on if there are any modifications that must be made to the proxy in order for the response to be in the correct format?

Frustrations excluding urls without ‘www’ from Nutch 1.7 crawl

I’m currently using Nutch 1.7 to crawl my domain. My issue is specific to URLs being indexed as www vs. non-www.

Specifically, after firing the crawl and index to Solr 4.5 then validating the results on the front-end with AJAX Solr, the search results page lists results/pages that are both ‘www’ and ” urls such as:


www.mywebsite.com
mywebsite.com
www.mywebsite.com/page1.html
mywebsite.com/page1.html

My understanding is that the url filtering aka regex-urlfilter.txt needs modification. Are there any regex/nutch experts that could suggest a solution?

Frustrations integrating AJAX Solr with Solr 4.5

I’m setting up Solr Search for my company’s domain and have stumbled onto roadblock after roadblock. Now that I’m at another obstacle my Google skills are again depleted. This project is almost three weeks in. Restorting to the Stackoverflow Gods again!

Frustrations with indexing Nutch 1.7 to Solr 4.5

I’m setting up Solr Search for my company’s domain and have stumbled onto roadblock after roadblock. Now that I’m at another obstacle my Google skills are pretty much depleted. This project is almost two weeks in with an aggressive timeline. I’ve had to resort to the Stackoverflow Gods for the first time…hopefully it works.
