How to highlight multiple keywords ?

[AmirKhan2]

I want to highlight all occurrences of multiple keywords. first i thought of highlighting all occurrences of one word and saving then overwriting the same file for highlighting the next word. But, when i implemented that i was facing a file locking issue. My next approach is to search for all the keywords on the single page and then highlight it. So, here's my code

pdf = fitz.open(pdfFile)
for keyword in keywords:
    for page in pdf:
        text_instances = page.searchFor(keyword)

        if len(text_instances) > 0:
            for inst in text_instances:
                highlight = page.addHighlightAnnot(inst)
                highlight.setColors(stroke=(1, 0, 0))
                highlight.update()
                foundDocList.append(pdfFile)

            pdf.save(f"{foundDocumentPath}/{os.path.splitext(os.path.basename(pdfFile))[0]}.pdf", garbage=4, deflate=True, clean=True)

but after implementing this i am getting this error mupdf: object out of range (21 0 R); xref size 21

Your code should work actually. At least at first sight. The PDF must be corrupt.Try to repair first before you do your stuff. E.g. mutool clean -ggggz file.pdf.

The. pdf is not corrupt it's working fine for single keyword highlight. The error arises when multiple keywords are concerned

[JorjMcKie]

Cannot reproduce. for this PDF
v110-changes.pdf
and this snippet:

>>> keywords
['pixmap', 'alpha', 'pymupdf']
>>> for kw in keywords:
	for page in doc:
		rl = page.search_for(kw)
		for r in rl:
			page.add_highlight_annot(r)

Everything works fine:
x.pdf

As an aside:
It is probably better to turn around the loop logic and stay on one page to mark every keyword. Then go to the next page.
