Hi, I need some clarifications on how works the Search Portlet.<br />1) The syntax supported is (fully?) compliant to Lucene query parser syntax? I mean, can I write something like this:  +title:word1 -title:word2 AND title:abc* ?If not, where can I find the complete reference of the syntax supported?<br />2) Suppose I&#39;d like to search for documents that contains word1 and NOT contain word2 in the title, if I use the following query: +title:word1 -title:word2    at first glance it works but if I browse the results set I notice that towards the end there are documents with title that contains both words (word1 and word2). I think this is why using the &#39;prohibit&#39; (-) operator make those documents get poor ranking and so they are  included at the end. Is it right? If so, how can I  prevent that these documents get included in the results set at all?<br />thanks in advance,<br />Marco<br />P.S: I am using Liferay 6.2 GA3
