Block-search/comment-search/permlink-search related issues

regarding the comment/permlink searches:

1. typo in name permalink should be changed to permlink

2. add support for comment-type - by default this api returns only root_posts (because this is the fastest view) but it allows to search by both comments and posts or only comments - https://api.syncad.com/#/Accounts/hafbe_endpoints.get_comment_permlinks

3. it might be up for disscussion but my vision of this api was on account page, similarly to votes history opens a modal with list of permlinks (with option of filtering by block-range/time-range/comment-type) and by chosing the permlink it opens new page with comment-search. I think it would simplify the usage - the account-name parameter doesn't exist in this case because you use it from account-page -> I think most users, in case they would be intresed in such informations they would look for them in their account-page. In current implementation i think it is kind of 'burried' in searches.

4. I think by default we should change the default block-range/time-range to for example last year or at least last month, the 1000 blocks were set because of api limitations that in the most part were fixed and it is possible to search by whole block-range

regarding the block-search:

1. the search by keys dissapeared? why?
2. same as in 4. in permlink-search the default block-range should be much higher

EDIT:

1. the << doesn't work for me ( >> works correctly)
2. in the comment-search API, I think by default the list of operations should be sorted ASC (not like in other operation lists), with ASC order we have clear order of the sequence ( 1. there were a post/comment, 2. then he altered comment_options, 3.then we can see the first vote on this post etc.)
