* Support searching commits with prefix syntax
For now, support auther: committer:
When more than one prefix is supplied is presented, the result is the union.
When different prefixes are supplied, the result is the intersection.
For example,
"author:alice author:bob"
=> the result is all commits authored by Alice OR Bob
"hello committer:alice"
=> the result is all commits committed by Alice AND has the keyword
'hello' in the message.
Note that there should NOT have any space after the colon(:) of the prefix.
For example,
"author:bill" => correct
"author: bill" => wrong
* Remove unneeded logging
* Add missing files of test repository
* Add missing repo_unit entries to test fixtures
* Update test cases
* Add tooltip for commits search button
* Update tooltip text
I have no idea about how to format it with line breaks.
* Make the usage example more real
* Add a test case
* Add new options struct for SearchCommits
* Prefer len(s) > 0 over s != ""
* Add NewSearchCommitsOptions
