Code is really messy and it will probably explode, so don't use it :)
git clone --recursive https://github.com/hanickadot/search-engine.git search-engine

cmake -B build .
cmake --build build
./build/build-index https://urlA https://urlBThis will crawle all urls provided and links on same servers. And build index in web/index directory.
Publish web/ somewhere on web or locally (using server.py) and open browser and type what you search for.
Put what you search into double quotes: "searching phrase"
You can go directly to closest hyperlink target in documents by clicking on hashtags next to links in search results.
Just copy address of the page including fragment and share it to someone :)
