Ask HN: Grep like tools for full text search?

You may get some mileage out of Swish-e[1].

And while it's not it's primary purpose, Lucene comes with some CLI programs[2]. They are there mainly as a demo, but if you feel like writing some code you might be able to adapt that to your needs.

I use Recoll:

https://www.lesbonscomptes.com/recoll/

There is a GUI, but it has a perfectly serviceable command-line interface as well. For example, this command lists all files with the exact phrase 'moved permanently':

    recoll -t -l '"moved permanently"'

And this command finds all files ending in '.py' and under a directory called 'Dropbox' that contain the exact words "import" and "logging":

    recoll -t -l "ext:py dir:Dropbox/ Import Logging"

It can take some time and effort to configure, but I have found it to be well worth it.

Ripgrep is good.

I use this for searching through multi repo setups for code, it should be great for multiple text documents:

Why not grep? Are you saying you want full text search with like, stemming and result ranking?

If I can piggyback on your question, my notes are in Word files and I sure wish I could grep those. I bet none of the answers at https://superuser.com/questions/70343/grep-in-microsoft-word work any more because Microsoft will keep changing the file format.

You search inside file using grep.

grep -Ril "term"
