[bioontology-support] missing search results in NCI Thesaurus

We are having some trouble with the search index not finding everything
that it should. The index was updated yesterday and a number of the
missing terms reported below are now found. Unfortunately there are still
some missing terms. We are looking at this problem again today.

Subject: [bioontology-support] missing search results in NCI Thesaurus


On the NCI Thesaurus, when the user searches for 'Age', the results do not
include some of the matches I was expecting:

Some expected results:
Age at First Live Birth
Age at Menarche
Age at Menopause
Age at Time of Vaccination
Age Started
Conception Age
Corrected Age
Postmenstrual Age
Subject Age

Search results contained 17 hits, but only a few from that list.  In
particular, the search results missed both "Age" and "Age-Years".
What is strange to me is that 'Age-Months' was on the list.  Can someone
help me better understand the search behavior of bioportal to explain
this?  Maybe its failing because the search string is on a stoplist or its
just too short/too common?
