Up in the right corner, there is a search box. I know, based on clicking on things from profiles, that there are modifiers that can be added to the search to filter the return. At the least, you can search for only postings by unique users.
From that, is there a guide that details the parameters that can be entered to filter search results?
EDIT Following @waxeagle's answer:
A general guide for looking around the site exists on the help page, only shows you how to use the search function to find tags. While there is a poorly formatted "Advanced Search TIPS" drop down on the sideboard of the results display page, I'd expect educational notes about these modifiers to have their own hyperlinked wiki-esque page.
If "Advanced Search Tips" includes each available modifier, it may serve to include it as its own page via the Help center. I'd even volunteer to try and write it if that is a thing that can be done. If there are modifiers not detailed in the tips, perhaps someone else would enjoy some fun.
TLDR: Can a guide that precisely describes the advanced methods for using the search function be added as a link on the help center?
