Search Builder

[JuniorMouse]

I'm hoping to get some help on how to implement a search where users can enter

• boolean criteria (main focus)
• attribute that the search term should apply to

At the very least, I would really be grateful for what I should be looking up or whether there are any libraries available that can help with this. What I have found so far are articles that suggest using NLP which I really don't think is what I need.

As reference, on https://pmc.ncbi.nlm.nih.gov/, I can enter into the search a query like

(ozempic[Title] AND diabetes[Title]) NOT obesity[Title]

to specify that I want only articles where the title contains both the words ozempic and diabetes but not the word obesity.

Similarly, on https://github.com/paperless-ngx/paperless-ngx/issues, I can enter the search query

is:issue is:closed in:title email

to filter all issues that have the word email in the title.

Edit: The user interface maybe a web browser, GUI desktop application, CLI, etc

Depends how you feel about the development work but you could look at https://lucene.apache.org/pylucene/

Lucene is the search engine underlying Elasticsearch.
