Hi @pmup999
我已經很久沒有改這個 repo 了，會需要久一點的時間溫習自己寫的程式碼，與審查及測試你提交的 PR，煩請稍等數天。

感謝你的 PR，很高興知道還有人使用自己做的工具 😊

Hi @pmup999
我已經瀏覽過你的 PR，整個修改方向沒有問題，但我會想要對一些細節作修改。

想請你先：

• 移除掉被註解掉的程式碼
• 統一使用空白字元進行縮排
  這樣我會比較好比較程式碼更動。

另外想請你確認一下這個 PR 是否有 開放讓維護者修改 的權限？
有開放權限給我的話，我直接接續做改動可以省下一些往返的時間

The default is to allow editing I have not changed

It's up to you to modify ！

It was too late yesterday. I wanted to say this to you to deal with. I just saw that it was not dealt with. I have revised it now. You can take a look.

Just learned how to add commits to your PR. I will add more in these days (or weeks). 😆

No problem, come on!

I will take this main idea from you:

• use the environment variable codequery_base_db_path to specify the db path, which is a good idea, especially for those people who work in non-git repositories (Finding db file in non-git repositories #26)

And I am still evaluating this idea: 👀

• search through multiple db files under the specified path

I would like to know more about your use cases:

• do you work on git-based repos?
• how do you move your newly-created local db file (like python.db ) to the codequery_base_db_path? how do you name these customized paths?
• why do you need to do searching through multiple db files? could you share your use cases?
• Have you ever encountered path issues while searching through codequery_base_db_path (especially when there are multiple db files)?

I use Java language, use maven for project building, when using Java framework he needs a lot of dependencies, but does not need to build All the code of this framework is DB, and only a part of the source code needs to be selectively built into DB, (because the computer I use is too old, so I need this method) because most of the source code does not need to be searched, at least I am think so. Because there is no code hint when writing code with vim, I often cannot remember the package path where Class or Interface is located when writing Java code. I mainly use it to check the package path to speed up writing.
Building multiple parts of a framework's source code into a DB is what I do.
My commit modifies the logic when querying autoload/codequery/query.vim:37, when querying codequery_base_db_path, he will query multiple times (multiple DB files), use .= to concatenate multiple queries
The following is my directory structure. When querying codequery_base_db_path, you need to judge the current file type (my submission should have) and select the corresponding type of directory.
I think it is appropriate to query multiple DBs of codequery_base_db_path, maybe consider adding options to handle queries in codequery_base_db_path separately.

E.g:
(Perhaps you should consider abbreviations for commonly used commands: CQ, CQB)
CodeQueryBase [Symbol Text ...] [optional '.doctype/java/[optional directory]' in $codequery_base_db_path/(current file type(java)) directory)]
Consider adding options to CodeQueryMakeDB when building

E.g:
CodeQueryMakeDB [ Base | (optionally move the build file to the $codequery_base_db_path/(current file type) directory)] [Base optional specific storage path]
When no specific storage path is specified, a prompt should be given (yes/no) when replacement is required

Okay.

Next month I have a couple of days, I will wrap up this PR but remove the multiple databases part.

For the multiple databases part, I will work with you to let those users in need can search through multiple databases by using a specific option.

ok, wish I had time then
