Solr's Built-In Filtering Mechanism

After successfully integrating Solr into my nodejs/mongodb application to enhance querying capabilities for a specific collection, I utilized mongo-connector to synchronize my mongodb with the Solr database. By customizing Solr fields, I was able to bring in necessary fields for advanced querying.

One crucial property within this collection is the visible attribute of a document that determines whether it is public (visible to all) or private (visible only to the owner). Before leveraging Solr, our server API calls managed this aspect by ensuring the visible status played a role in requests. However, I am now unsure how to replicate this functionality using Solr.

The goal is to access Solr directly from the client app through Solr's query parameters on our client-side search/filter page. Is there a method to automatically append a filter to all Solr calls specifying visible = true, hence preventing private documents from being included in the response? Ideally, I prefer not to implement this on the client side to avoid exposing these documents.

Any guidance on this matter would be highly valued!

Answer №1

A parameter list can be added to a definition for a requestHandler in order to append an fq statement to all requests. The solution provided on the wiki for this use case includes adding the following code:

<lst name="appends">
  <!-- Ensures that only inStock products are returned, regardless of other fq statements -->
  <str name="fq">inStock:true</str>
</lst>
