It frequently happens that I want to find my old answer. The list of answers on my page consists of 35 pages, so searching in it using my browser search is too time consuming. On the other hand, if I enter the search terms in the "questions search" it does not show me those questions where the terms occur in answers. I understand that expanding capabilities of search can be difficult, though very desirable. But it seems that adding a feature which displays all answers of a given user in one page (instead of in 35 pages) must be easy.
This isn't exactly about the feature you asked for, but let me leave here a brief comment. (Hopefully, some of the information here might be useful.)
One possibility to get list of all your answers (or questions) in a more compact form then here on the site is to use SEDE. (With the caveat that the data in SEDE are only updated once a week, so you won't find the most recent posts there.)
Basic knowledge of SQL helps when using SEDE - but many various queries already exist, so often you can find some queries and simply change the parameters.
Let us compare what some search result look like if you use SEDE and if you user built-in search engine.
You can limit the search to a specific user by using user:25510 or simply user:me if you're looking for your posts. (If you go to your profile page or to the profile of some other user, the modifier
user:userid is already prefilled in the search box.) You can restrict the search to answers/questions using is:a or is:q.
To get corresponding results in SEDE you need to specify this in the query. (For example, in the table Posts we have
PostTypeId=1 for questions and
PostTypeId=2 for answers.)
I will add that the SEDE queries linked above only search in the body. The table Posts contains also the field Title, which can be used if you want to search for posts using the title. Here are queries searching for questions and answers of a specific user based on a word/phrase contained in the title.
