While the Suggest feature is intended to motivate searchers to refine their queries, it generally works well for that purpose only if the additional modifiers are at the end of the query.
If you're targeting [great red widgets], eg, but [great widgets] is extremely popular, you may find that after searchers have typed in just g-r-e-a that [great widgets] is suggested... and many searchers go with that.
Suggest can paradoxically lead to more searches for the general phrase... not the disambiguated phrase that might have been searched without it. This can also drain off a lot of traffic.
