Back-of-Book Index Verification — Match ~1,100 Words to Page Numbers in a 278-Page PDF

I need someone to verify and complete a back-of-book index for a non-fiction book. The index word list already exists (about 1,100 entries, including plural and possessive variants). Your job is to search the full text and confirm the correct page number(s) for every word.

Scope:

Source: a 278-page PDF (editable, not scanned)
Index range: page xii (Preface) through page 256 (Glossary)
Word list: provided as a Word document, already includes plurals and possessive forms
You must find every page number for every word using a whole word search, not partial matches
Many words contain hyphens, forward slashes, apostrophes, or are followed by asterisks in the text. These must not break the search or cause missed matches
Any word genuinely not present in the text should be flagged in a separate list, not silently dropped
Final output: the index list with accurate page numbers, formatted with proper spacing around page number commas, delivered as a PDF

Why this matters:
Two previous indexers failed this task because their search missed words with special characters or asterisks attached. Accuracy is the entire point of this job. If you cannot guarantee a thorough whole-word search across the full document, please do not bid.

Deliverables:

Completed index with page numbers, formatted per instructions
Separate list of any index words not found in the source text
Files/scripts used, so the process can be reused for future book updates

Timeline: 5 to 7 days from file handoff

Budget: Fixed price, paid via milestone/escrow

Ideal skills: Attention to detail, experience with PDF text search or Python-based text processing (regex, PyMuPDF, or similar), prior indexing or proofreading work is a plus
