Search functionality is not fully functional and is inconsistent between web app instances

[xhoenner]

Steps to reproduce

Go to the production web app landing page - version 3.35.4
Search for A69-1602-26876.
In another tab, do the exact same thing except on the dev web app, same version used.

Try the same thing on both instances with A69-1602-24963.

Try the same thing on both instances with VR2W-120773

What happens

Despite the fact that this tag exists in both the production and dev databases (e.g. https://animaltracking.aodn.org.au/tag/show/134076088), there is an inconsistency in the results returned by the web apps.

The production web app returns that nothing matched this query, see screenshot below

On the dev instance a result is returned, see screenshot below

For A69-1602-24963, no search result is returned on both instances despite the fact that this tag exists in both databases.

For VR2W-120773, the number of results differ between the two web app instances

What should happen

1. Results should be consistent between web app instances.
2. When searching for a given tag that has been registered in the database, the web app should return the corresponding result
3. When searching for a given receiver that has been registered in the database, the web app should return the same number of results for each instance
