salinic 0.2.0

Search abstraction layer

Salinic

Salinic - provides modular search. It features a unified, familiar API that allows you to plug in different search backends. Currently it supports only Xapian backend.

Usage

Declare your search schema:

from typing import Optional

from salinic.field import IdField, KeywordField, TextField
from salinic.schema import Schema


class IndexEntity(Schema):
    id: str = IdField(primary_key=True)
    user_id: str
    parent_id: str
    title: str = TextField()
    text: Optional[str] = TextField()
    tags: list[str] | None = KeywordField()

Index your documents:

    from salinic import Session, create_engine

    engine = create_engine("xapian:////search_index")
    session = Session(engine)

    for document in all_your_documents():
        entity = IndexEntity(
            id=str(document.id),
            user_id=str(document.user_id),
            parent_id=document.parent_id,
            title=document.title,
            text=document.text,
            tags=document.tags
        )
        session.add(entity)

Search your documents:

    from salinic import Session, create_engine

    engine = create_engine("xapian:////search_index")
    session = Session(engine)

    sq = Search(IndexEntity).query(" your query string ")

    for found in session.exec(sq):
        print(found)  # found is instance of IndexEntity
