FS4SP – The truth about the u2029 delimiter


Hi

 

Having seen many entries on this I wanted to clarify one point about the delimiter \u2029 in Fast Search for SP2010.

 

The delimiter “\u2029” only works in the context of Pipeline Extensibility.

 

See http://social.technet.microsoft.com/wiki/contents/articles/1144.multi-value-property-support-in-fast-search-server-for-sharepoint.aspx
.

“In the input to the extensibility stage the special character U+2029 is used as a separator for multi-valued crawled properties”.

 

In other words, in order to send a multi-valued CP to the Pipeline Ext we separate the values with the \u2029 separator in the input xml.

 

When processing the output xml we look back at the separator (UTF-8 encoded) to build back a multi-valued CP in the Document Processing.

 

To support single-valued CP with custom delimiter (i.e. ‘;’) , you need to go through the Pipeline Ext as described here : http://social.technet.microsoft.com/Forums/en-US/fastsharepoint/thread/a4285ae0-c899-4c6c-ab24-032e70d4525d

 

Note: Inserting the separator in your content directly will not work since the Crawled Property sent to the Document Processing would still be single-valued.

  1. Hi Nicolas,

    Is this still valid in SP2013? Is there a delimiter that can be used in the content?

    Thank you,

    Ivan
