I use Preview a lot when reading PDF’s and the sort. I mentioned a couple of days ago about exporting PDF’s to text files. Anyway I want to mention a couple of quick Preview searching tips to tide you over. They are simple but useful.
One quick tip I would like to share is the ability to order search results by page. This is very useful if you have a massive document. By ordering the result by page it will order the results by the frequency in which they appear on the page. I think it is more useful as it will show you less result.
Another quick little tip is to add the plus and minus signs into the search results. These will enable you to narrow down your search results. It works in a similar way to how Google uses the plus and minus operators.
A couple of simple tricks. I am sorry this post isn’t longer. I really don’t have any time at the moment.
