PDF Index

I want an index of my pdf files stored in Zotero. Other repositories that may be of interest include a server that responds to /query?q=search terms and a client that debounces requests to that server and displays results on the fly.

See this blog post for more information about the project: https://jcuenod.github.io/bibletech/2021/07/26/full-text-search-for-pdfs/

Usage

Build the Index

Be sure to set the root variable in config.json to the root folder under which pdfindex should look for pdfs.

node create-index.js

Query the Index

SELECT
    name,
    page,
    snippet(pages, 2, '<b>', '</b>', '', 15)
FROM
    pages,
    metadata
WHERE
    content MATCH 'NEAR("sabbath" "fire")'
AND
    pages.id = metadata.rowid;

The format for snippet is:

snippet(pages, 2, '<b>', '</b>', '', 15)

• pages: Name of the table
• 2: Index of the column (zero based)
• <b>: String to inject before a matching token
• </b>: String to inject after a matching token
• '': String to inject at beginning and end of string if there is not a matching token there
• 15: Number of tokens to return (i.e. length of snippet)

Output Example

Weinfeld_1981_Sabbath, temple, and the enthronement of the Lord.pdf|3.0|shall not burn <b>fire</b> in any of your dwellings on the <b>Sabbath</b>״ (Ex. 35:5
