At the last Drupal Indy User Group meeting, I did a presentation on integrating Openlayers and Apache Solr. In the presentation, I walk you through how to setup and configure the modules necessary to display search results on a map in Drupal 7. This is the same basic process which we used on Energy.gov.

The video is about 45 minutes long, so here is a general outline of the presentation. Be sure to watch the entire video or you will not see how all of the pieces are integrated:

1. How to Geocode Content
2. Sending Geocoded Content to Solr
3. Local Solr with Apache Solr
4. Openlayers
5. Adding Solr Results to a Map
6. Placing a Map on the Search Page
7. Viewing Search Results on the Map

Modules covered in the video

• Apache Solr
• Open Layers
• Openlayers Apachesolr Integration
• Geofield
• Geocoder

Update...

To Help facility setting up Apache Solr with Local Solr I created this repository: https://github.com/treehouseagency/local-solr-config. It contains all of the files necessary to run solr with local solr on Mac OSX.

Instructions to Run:

1. Checkout the repo.
2. Change to the "examples" directory
3. run "java -jar start.jar"
4. Profit!
