> Some small improvements:
>   * Adds a TermsEnum.cacheCurrentTerm "hint" (codec can make this a no-op)
>   * Removes the FTE.useTermsCache
>   * Changes MTQ's TermCollector API to accept the TermsEnum so collectors can eg call
.docFreq directly
>   * Adds expert ctor to TermQuery allowing you to pass in the docFreq
