Hi ,
I am using MarkLogic 6.0 Rest Api's to search content and I have an query about
facets.
I am getting by default facet for an element like "author" as below in my
search result from content:
<search:facet name="author" type="xs:string">
<search:facet-value name="" count="87462"/>
<search:facet-value name=" " count="287"></search:facet-value>
<search:facet-value name=" " count="7892"></search:facet-value>
<search:facet-value name=" Marino" count="1">Marino</search:facet-value>
<search:facet-value name="<i>from</i> ABC News" count="7"><i>from</i> ABC
News</search:facet-value>
</search:facet>
In above result , I am getting facet-value for those author elements which
values are null, single or more space, new line null values and text values as
by default behavior of REST API's.
As per my requirement, I don't want those null, single or more space and new
line null values, I want only those facet-values which contains only text value
as below.
<search:facet name="author" type="xs:string">
<search:facet-value name=" Marino" count="1">Marino</search:facet-value>
<search:facet-value name="<i>from</i> ABC News" count="7"><i>from</i> ABC
News</search:facet-value>
</search:facet>
I created following constraint in search option file and created range path
index (*:author[. ne ""][. ne " "]) in MarkLogic also.
<search:constraint name="author">
<search:range
collation="http://marklogic.com/collation//S2<http://marklogic.com/collation/S2>"
type="xs:string" facet="true">
<search:facet-option>ascending</search:facet-option>
<search:facet-option>limit=10</search:facet-option>
<search:path-index>*:author[. ne ""][. ne "
"]</search:path-index>
</search:range>
</search:constraint>
But I am able to remove only facet-value for author's element null values. I
need to also remove facet values for single or more space and new line null
values.
And we can't use *:author[fn:normalize-space(.) ne ""] as path index.
Is there any solution to achieve this goal?
