1.3.4.3.2.8.  Phrase search "" (specific order of terms)

For a phrase search (specific sequence of terms), place the entire search term in quotation marks.

Condition: All search terms must be found. There must be neither anything missing nor anything in between. There may be other terms outside the search term. The phrase search tolerates Stemming[18] and decomposition of compound words.

Example:

A search with

"Schraube mit Mutter"

also finds

Sechskantschrauben mit
Muttern

Here in this example the hit is made by accordance in the project path.

For a better understanding, two important differences between phrase search and exact search should be mentioned:

  • Stemming:

    Phrase search:

    "mit gebördelt Rohr"

    finds "flared couplings" (stemming tolerated)

    Exact search:

    {mit gebördelt Rohr}

    does not find "with flared pipe" (Stemming not tolerated)

  • Compound words (mainly 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 "cap screw with nut".
