PDF attachment content and REGEX handy usages

cadudesun
Hi,

I need to explore PDF attachment content in advance search. So far I've been using Regex capabilities very few and my expectation is that it is quite powerful.

a) I would appreciate any tip or suggestion regarding handy Regex operators/syntax/usages to mining data in a literature review process using Zotero.

b) To search exact expressions using Regex, are the "quotation marks" necessary?

Many thanks,
Cadu

    Handy tip (completely unrelated): To query two words within N words of each other, try
    word1(?:\s+\w+){0,N}\s+word2
    E.g., to query for "secondary data" or "secondary analysis of data", use secondary(?:\s+\w+){0,2}\s+data

    ;-)

    oh and for (b) the answer is no. That will just search for quotation marks as well.

    also, for the basics
    the cheat sheet is good: http://www.cheatography.com/davechild/cheat-sheets/regular-expressions/

    b) in addition to what aurimas says - regexes are literal by default, i.e.
    /find this sentence/ (you don't need the slashes in Zotero) will only return true when you have exactly "find this sentence" in the document.

    This is where I learned regexp: http://www.regular-expressions.info/

    I remember seeing this at the time, but not paying much attention to it. But can somebody please clarify WHERE you do these regex searches? Can we use those in the Zotero Advanced search dialog box?

    It's in the advanced search box https://i.imgur.com/KA0wQbU.png
