Head/Tail Analysis Relies on User Signals
Looking at only the query analysis is only half the job. Lucidworks ingests users’ behaviors too: what they clicked on, what they didn’t, and what they rewrote. We feed these signals into Fusion to find synonyms, misspellings, and more popular “head” queries. For example, if users frequently type “manger” and “manager” in succession If “carpet” typically follows “rug” Lucidworks learns those are synonyms.
Head/Tail Analysis allows us to look at historical behavior and rewrite the query for greater relevance.
