Phrase search
"" (certain sequence of terms)
In order to
perform a Phrase
search (exact order of terms), put the whole search term in
double
quotes.
Condition: All
search terms have to be found. Nothing may be missing, nothing may be in
between. Outside the search term other terms may occur. The Phrase search tolerates
stemming[142] and splitting of compound words (especially
German).
Example:
A search
with
"bolt with nut"
also
finds
Hexagonal bolt with nut
For a better
understanding two important differences between Phrase search and Exact search shall be
pointed out:
Stemming:
Phrase search:
"flared coupling"
finds
"flared couplings" (stemming tolerated)
Exact search:
{flared coupling}
does
not find "flared couplings" (stemming not
tolerated)
Compound words (especially relevant in
German):
Phrase search:
"Schraube mit Mutter"
also
finds "Zylinderschraube mit Mutter". (The compound word
"Zylinderschraube" has been treated split in its subparts.)
Exact search:
{Schraube mit Mutter}
does
not find "Zylinderschraube mit
Mutter".
