Personally think is the search problem tag + Title contains tags in the keyword.
Like your question tag is PHP. This question (https://segmentfault.com/q/1010000000095152) does not have a label but the topic has the same keyword as the tag php then should be randomly selected, of course, there should be problems in descending order of the generated time. For reference only.

I understand that the current problem is first broken into keywords, merging the label of the problem.

How to Dismantle? is the participle, participle also has a lot of open source implementation scheme.

Then it's searching for these concerns.

Search can use third-party search, simple Baidu, GOOGLE
You can also make your own search function, simple xunsearch, complex sphinx\coreseek, suggest to use their own search function, you can customize the relevance and sorting.
