Searching with underscore returns records that don't contain the search term

Scenario:

Searching for 'A__B' returns records that contains the following:

• Records that contains 'A__B'
• Records that contains 'A_B'
• Records that contains 'A B'
• Records that contains 'A' and also 'B'

Explanation:

1. Multiple underscores are converted to single underscore (e.g. 'A__B' will be converted to 'A_B' and 'A__1' will be converted to 'A_1').
2. Underscore not followed by a number will be replaced by a single space, hence searching for 'A_B' will be converted to searching for 'A B'.
3. Underscore followed by a number will stay the same, hence searching for 'A_1' will be searched as 'A_1'.

Conclusion:

Searching for terms containing single/ multiple underscores, not followed by a number will be broken into two separated terms which will cause Primo to return irrelevant records
