Using the Query Operators
Using Wildcards
You can use wildcards to obtain special results. For example, you can find
documents that contain words that have similar spellings but are not stemmed
variants. For example,
plan stems into plans and planning but not plane or
planet . With wildcards, you can find all of these words.
Some characters, such as * and ?, automatically indicate a wildcard-based search
and do not require you to use the
<WILDCARD
operator as part of the
expression.
<WILDCARD>
Finds documents that contain the
wildcard characters in the search string.
You can use this to get words that have
some similar spellings but which would
not be found by stemming the word.
Some characters, such as * and ?,
automatically indicate a wildcard-based
search, so you don’t have to include the
word
<WILDCARD>
.
<WILDCARD> plan*
Finds documents that contain plan , plane ,
and planet as well as any word that begins
with plan , such as planned , plans , and
planetopolis .
See the next section for more details and
examples.
<WORD>
Finds documents that contain the
specified word.
<WORD> theme
Finds documents that contain theme ,
thematic , themes , and other words that
stem from theme .
