[Bulk search] Odd behavior of the bulk search

[Lhorus6]

Description

When I search for multiple entities using bulk search, I observe some strange behavior (especially with File observables), examples:

• File observables appear more than once.
• When I delete the list of entities I'm looking for, results are still displayed in some cases.

Environment

OCTI 6.1.8

Reproducible Steps

To do in "testing" platform

Duplicate results

Steps to create the smallest reproducible scenario:

1. Go to the bulk search
2. Look for:

93.115.0.49
ns-1156.awsdns-16.org
f9bdeca0e2057b0e334c849ff918bdbe49abd1056a285fed1239c9948040496a

Results remaining after deletion

Steps to create the smallest reproducible scenario:

1. Go to the bulk search
2. Look for:

93.115.0.49
ns-1156.awsdns-16.org
f9bdeca0e2057b0e334c849ff918bdbe49abd1056a285fed1239c9948040496a

3. Remove one element at a time from the search (remove the hash, then the domain, then the IP)
