I installed it. There is no gui right?

Could you give me an example of command to index and search inside the file? Thank you so much

I would like to search only in the content of a text, but in an intelligent way.

So if in the text file it says: "Hardware is the physical part of the computer and software is the logical part"

and to find it I wrote: "Hardware is the part of the computer that we can touch while software is the programs"

It should be able to find it for me anyway, right?

thanks, now i try to install it

I looked at elasticsearch but its quite expensive. Are there any free or cheaper alternatives? I also tried Papermerge but the search doesn't work, even if I try to search for exact phrases or the file name. Is there something I may be forgetting to do?The file is already text without images
