When I complained on the users' list, the developer suggested that I upgrade my operating system. On very long documents (1000 or more pages, I suppose), the entire display area of the window is blank. The size of the white band is proportional to the length of the document. This app contains bugs which never get fixed.įor example, there is apparently an error where the size of the display part of the main window is miscalculated so that on long documents a white band appears at the top and grows shorter as you scroll through the document. If you require anything more than the most basic search functionality, you will need to use a different app. If you need to annotate PDFs, there is nothing better than Skim. In other words, it is unlikely Skim's search capabilities are going to get any better.

The developer said Skim was using the search capabilities provided by Apple's PDFKit so if you want improved search, then you should talk to Apple. I searched Skim's 'Issues' page on GitHub and found that someone had brought this to the developer's attention a few years ago. It immediately found the exact page I needed-where the words 'capitalization' and 'infinitive' appeared in different parts of the page, about three sentences apart. I opened the document in Preview and searched for 'capital* AND infinitive'. produce zero search results And that exhausts the Skim search capabilities. The exact phrases 'capital infinitive', 'infinitive capital', 'infinitive capitalization', 'capitalize infinitive', etc. But there is no way to find where it appears anywhere on the same page with some form of 'capital'. Any search for two or more words will be an exact phrase search. However, as soon as you hit the space bar, you are locked into a search for the exact word you typed. If you type 'capital', it will show pages that contain capital, capitals, capitalize, and capitalization.

In Skim, you can find where any form of 'capital' appears. And the word 'infinitive' also needed to appear anywhere on those pages. I needed pages that used the words capital, capitals, capitalize or capitalization. The other day I needed to find the title capitalization rules for infinitives. If you need to find a page where two words appear separately, then you are out of luck

Search doesn't support wildcards or booleans. Skim is a great app, but it has one significant limitation.
