IF NO RECORDS are retrieved in a search which included parenthetical
information, the system will offer two options: 1) BROWSE word index,
and 2) Show records with a specific WORD. |
For example: |
art and (skid row) |
|---|
|
Retrieves no records.
If you choose BROWSE word index, the system will show the
number
of occurrences of each word in your failed search statement. You
may select a term and move into the word index with that term. From
the word index, you may browse forward or backward and/or select
records for a specific term.
If you choose Show records with a specific WORD, the system
will
show the number of occurrences of each word in your failed search
statement. You may elect to do an immediate WORD search on any term
that appeared in your failed search statement.

WORD IGNORED means that a word you used in your search statement does not
appear in the searchable fields. The system will search the other words in
your search statement and post the results for each word. A message
"[word] is not in any records - WORD IGNORED" will appear with the word
which has no records. |
For example: |
highrolling and (skid row) |
|---|
|
Retrieves no records.
The system will combine the terms "skid" and "row" and report the
number of occurrences of each term and the number of records in which
"skid" and "row" appear. The system will also report "highrolling "
is not in any records - WORD IGNORED." The system will offer the
option to view any records retrieved with the other terms.
NOTE: Check that the word is spelled correctly.
