Does hy­phen­ation af­fect search?

It de­pends on the search en­gine. Google and Ya­hoo prop­er­ly han­dle the soft-​hyphen char­ac­ter. Mi­crosoft and Ask im­prop­er­ly treat soft-​hyphens as word breaks. For­tu­nate­ly, Google and Ya­hoo com­prise more than 90% of the search mar­ket.

Be­cause Word­Press search queries the data­base — and hy­phen­ation is not stored to the database-​local search is not af­fect­ed.
