Bitbucket Cloud's code search only indexes files smaller than 320 KB: https://confluence.atlassian.com/bitbucket/search-873876782.html

Some customers have requirements to search their code base on files larger than 320 KB. One example is a requirement to search the code base for any database reference changes to be able to work with their DBAs on any predicted DB spikes when deploying their code. Since they are unable to search all files within Bitbucket Cloud's code search, they are unable to use this functionality in the aforementioned fashion.

It would benefit us to either:
1.) Increase the size that the code search indexes files
2.) Provide the ability to configure or request on a repository basis how large of a file to be indexed in the code search

Workaround:
Search code locally using code editors
