Question

I am trying to write a lucene query to retrieve some pages in my website so I have the following:

string.Format("nodeName: ({0})^7 bodyText: ({0})^6", _searchTerm)

which means it will search for content that either has the nodeName or the bodyText that includes the _searchTerm variable

where I am struggling is that I also want it to not include any results that have a hideInNav flag set to 1 so I tried:

string.Format("nodeName: ({0})^7 bodyText: ({0})^6 +hideInNav: NOT(1)", _searchTerm)

However this is throwing up the following error:

Encountered " <NOT> "NOT "" at line 1, column 140.
Was expecting one of:
   "(" ...
   "*" ...
   <QUOTED> ...
   <TERM> ...
   <PREFIXTERM> ...
   <WILDTERM> ...
   "[" ...
   "{" ...
   <NUMBER> ...

As far as I can tell the query does have a ( after the NOT so I’m stumped as to where this is being expected

Answer 1

Try this query:

string.Format("nodeName: ({0})^7 bodyText: ({0})^6 !hideInNav: (1)", _searchTerm)

The exclamation mark can also be changed to NOT:

string.Format("nodeName: ({0})^7 bodyText: ({0})^6 NOT hideInNav: (1)", _searchTerm)

See this page for an overview of the Lucene Query syntax (it’s not the current version but I doubt it changed a lot)

Edit: maybe reversing you hideInNave statement will fix it:

string.Format(“nodeName: ({0})^7 bodyText: ({0})^6 +hideInNav: (0)”, _searchTerm) to check if it is zero or check if it is zero.
