ZEBRAsearchkohafields is the underlying API for searching zebra for KOHA internal use |

you receive an array of XML records. |
|
|

The routine also has a flag $fordisplay and if it is set to 1 it will return the @results as an array of Perl hashes so that your previous |

search results templates do actually work. |

However more advanced search frontends will be available and this routine can serve as the connecting API for circulation and serials management |

This routine will also take CCL,CQL or PQF queries and pass them straight to the server |
