Google scholar is good, but following search engine is great, specially when you are looking for thesis.

Dear Reza Barati,

Currently, advanced search tools, unfortunately, should be searched on other information portals and in search engines containing advanced search options. Unfortunately, research portal, authors, etc. is not available on the Research Gate portal. Many users of the Research Gate portal indicate that it would be useful to enrich the publication search tool, authors, .. with additional, advanced options. Enriching search algorithms with additional options could be done in the same way as it does in Google search. Some similar solutions of advanced search functions already exist on some other social media portals.

Best wishes

You can use both Google scholar and Research Gate to do so
