Dear Drupal Experts

Currently I use apache solr 3.6.2 for search engine in a Drupal 715 environment. Apache solr, indexes the document, I search based on the keyword and gets document list. So far so good.

I need to enhance it. When I add the document (actually these are resumes), I need to add certain fields like age, experience years, salary etc.

So that while searching the documents, I can add the filters accordingly to get more relevant documents.

Now my BIIGEST worry is how do I proceed.

1. Do I need to modify the schema file to add fields for age, experience, salary

2. Do I need to implement some special hooks in my custom module, so that I can add the fields like age, experience (any examples if you have please share) during indexing.

3. While searching, do I need to implement any specific hook, so that I can add the filters for age, experience etc.., if so , pls share the examples if you have.

Thanks

Kamal
