Filter out bleve search results

[Benjamin BALET]

Hi,

I'm experimenting bleve on an inventory project that allows a global search on all stores. But users can view only the items stored in stores they are granted to access.

My initial solution was to iterate on the searchresults / Hits array and to build a new array by appending only the items users can view (Bleve Doc ID is a joined string of Item ID and storage ID).

I was just wondering if there is a way to safely delete some Hits or another solution.

In general trying to filter out undesirable search results after the search has been completed is problematic.  It means you give up features like pagination, because you never know how many items to request, since you end up throwing some away.

A better approach is to index this additional data, and add the filters to the users search query.  So, in your example, if you index a field with each item called "store" using the keyword analyzer (because you only want exact matches on it).  Then when a user searches for X, you instead do the following search:

Conjunction combining

  - Users search X

  - Disjunction consisting of one or more TermSearch for store IDs the user should have access to

Let me know if this isn't clear or if you have more questions about this approach.

Marty, would you mind sharing just a small code sample please?
