Hi Emi! If I'm understanding you correctly, you would like to filter for highlights, data and insights from project XYZ, with a title that contains "abc", in the last quarter? You should be able to do this by:
Setting the "Anything" filter to Highlights, Data and Insights
Setting the "Anywhere" filter to your chosen project
Setting the "Anytime" filter to the last quarter (or 90 days)
Selecting the "Title only" filter
Searching for your desired keywords in quotation marks
Let me know if this doesn't suit your requirements - as always, happy to jump on a call if you have any other feedback!
