I posted a question What wildcard operators are supported in Kronos WFC searches? on SO.
The question includes an incomplete list of wildcard operators I was able to find through my own experimentation. After the posting my question, I began wondering whether I should have posted my information as a self-answer.
On one hand, including my research in the question shows the research effort that went into the question before posting. It shows the attempts I've made so far, and indicates that the problem hasn't been fully solved.
On the other hand, posting as a separate answer could be more helpful for future readers, as the information may be considered a solution for others with the same issue.
When asking a question which we have an incomplete answer for, should it be included as part of the question? Or should it be posted as a separate answer?
