One Way Synonyms

One-way synonyms

Sometimes, searches for one term should also yield results for another, but not in reverse. This is where one-way synonyms are convenient.

In the example below, searches for “tablet” should logically return “iPad” since iPads are just one type of tablet.

1
"tablet" ⇒ "iPad"

However, “iPad” is more specific than “tablet,” and probably shouldn’t return generic matches for “tablet”:

1
"iPad" ⇏ "tablet"

One-way synonyms are stored very similarly to regular synonyms; the only difference is that the type attribute is now oneWaySynonym.
