flx-isearch fails to search terms like "*symbol-table*"

[tuhdo]

To reproduce:

• Open an empty buffer, insert *symbol-table* there.
• M-x flx-isearch-forward
• Type symbol.
• The search fails.

This seems to be a problem with my usage of Emacs Regex. Given symbol, flx-isearch will search for \\_<*symbol-table*\\_>. Strangely, Emacs doesn't seem to be detecting symbols in regex correctly.

Do you have any ideas?
