Re: [google-appengine] Error in search - AST is missing nil root

[Amy Unruh]

Paxti,

What does your final queryString look like? And, could you include a stack trace?

Also, are you seeing this with the dev app server, or for your deployed app?

Hi,

I´m using Google Search API and at the time of making the search:

QueryOptions options = QueryOptions.newBuilder().setLimit(limit).setOffset(offset).build;

queryString+="name:\""+name+"\"";

Query query = Query.newBuilder().setOptions(options).build(queryString);

Results<ScoredDocument> results = index.search(query); 

I´m getting a SearchQueryException saying the following:

AST is missing nil root name:"value"

Name is an existing field and I don´t know why am I getting this error.

Anyone could help me?

Thanks :)

Hi,

as you said, this only happens when I am running locally, when I deployed on GAE it works.

Thank you :)

Paxti,

Thanks for the information.  Could you also post an example of a queryString that triggers this error, and the stack trace?  You can email to me directly if you'd prefer.

Hi Amy,

the problem comes with any request. For example with a simple request like "key":"value".

But as I said, when I deployed it at GAE and using "complex" queries including AND and OR operators it works well.

I have another question: it appears that search is not working properly when a value for an specific key is a single character. So if I have a key "key" with a value containing "a b c" and my search is key:"a", then no result is returned.

Thanks for your attention :)

hi Paxti,

I can't reproduce your issue using 1.7.2.1 (if I'm understanding it correctly).  Can you file a report for it here?:

 http://code.google.com/p/googleappengine/issues/list?can=2&q=Component=FullTextSearch

Please include a specific example query string that triggers the error (that is, not just a description of the syntax as below, but the actual query string), and also the error stack trace that you get. 

Note that you should not enclose the field name in quotes in the query.  So if you have a field called 'category', this query should be okay:

  category:food

as should this:

  category:"food"

but this is a parse error:

 "category":"food"
