Use `terms` instead of `term`

[dhruvkb]

Problem

In the search controller, when performing filtering for more than one value, we use an array of term queries instead of using terms.

Description

Replace the array of term queries with a singular term query. According to the ES docs, the terms query is functionally identical to term.

Additional context

For an example, a terms query is used just a few lines below in the same file, inside the _exclude_filtered function.
