Find & Highlight Keywords (somehow)

[mikhail_fil]

I have a huge library of books and research papers (14k)
Lets say i do a following search:
"Hebbian Learning" "Long-Term Potentiation (LTP)" "Short-Term Potentiation (STP)" "Dopamine Hypothesis" "Split-Brain Theory" "Information Integration Theory" "Free Energy Principle" "Neural Correlates of Consciousness (NCC)" "Hierarchical Temporal Memory (HTM)" "Neural Darwinism" "Theory of Mind"
How can I "tell" which keywords were found where? Is there a temporary way to see which is found in which books metadata? Is there a way to then apply permanent "highlight" to that books Comment? or Tag it?
for full text search, i've been using Adobe Acrobat Catalog, but it would be great if this could be done in Calibre.

PDF XChange Editor can search across all open documents or within a folder/subfolder for a given expression and highlight all occurrences. Only PDF files, evidently...

edit: oh that's more applicable to FTS, I see you want to modify metadata, rather than text content

I assume the search terms would be ORd.

Rather than modifying Comments for the books that satisfy the search criteria, I would probably Mark the books, and add the search-expression to a custom long text column via :



But that doesn't answer your primary question: "In which metadata columns were the search terms found?" - I'm not aware of any way of getting that - other than eyeballing the Book Details panel. And, I suspect the search of a book's metadata would cease when a positive result is found - e.g. if "Hebbian Learning" appeared in a book's title the search would stop for that book.

I'm not familiar with that tool, the Drop Search Results plugin can use a results list from other search tools (Windows Search, File Locator, Agent Ransack, X1, Everything and others) to Mark books in a calibre library.

And, there's another plugin that might be relevant - Multi-column Search.

calibre has built in full text search and you can tag or mark any book that matches a full text query. As for seeing which metadata item matched I'm afraid that's not possible.

Maybe a janky way to add tags automatically for your database could be the Extract People and Other Metadata plugin (https://www.mobileread.com/forums/sh....php?p=4287169)

I usually use my library for fanfiction, which comes with (messy) metadata tags created by the author to let readers know what to expect. If you could create tags for your library you could use tag:"=Theory" and figure out which files contained which tags by looking in the book details column.

This isn't really temporary, you'd be using this as a permanent replacement for the fulltext search. You would have to figure out how make different variations of the same topic into the same tag I suppose, but that would probably be easily done with some regex.
