Description

As duplicates of existing files check existed in different files, it was not efficient and caused redundancy. Applied new logic to check_index_exists to adapt to different cases and removed the redundant code. I have written tests for different scenarios and manually tested it as well.

Thanks so much for the PR, @harikrishnatp! Really appreciate you keeping this in mind :) Would you be able to do an initial review here, @axif0? :)

When trying the PR, I'm getting FileNotFoundError error, I tried

scribe-data g -a -dt verbs -od test

Actually in arabic verbs there is no query_verbs.sparql file exists.

@harikrishnatp, Did you also encounter the same error, or is it just me?

[harikrishnatp]

Yes @axif0, I'm also getting the same error

[andrewtavis]

Maybe there's an issue with the way that the default query is being set? Generally it checks to see if there's a .sparql file with *_1.sparql and then it doesn't check for the one that doesn't have a number at the end 🤔
