5.3.8.  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[4] 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".
