Modifying search query for Full Text Search

Hi all,Alfresco search will search also the contents and I have a constraint that the search should not search and get the details if the search text is a XML tag.For instance If I have a xml called Sample.xml,<sample-xml> ABCDEFGH</sample-xml>If I enter the text "sample-xml", it sh

Hi

If you mean "I do not want to find the tages <sample.xml> in the content of my XML file", then this is down to your converter from xml to text.
I believe the default is to strip out tags ??

Hi Jeya,

I am not sure if this would help you but I can mention query which helps to filter some specific text :
In the below example you will not be able to search content having text as "fox"
For e.g. - the Lucene query you can check in nodebrowser

+(TEXT:*) -(TEXT:fox)

Here "+" will be considered as "must match "
"-" as "must not match"

Now if you want to apply this when you are searching from search box then you have to make change at API level.
SearchContext is the class which is basically used for building query . You can check buildQuery() method.

Thanks,

Hi Amita,

Lucene search is not considering "<" and ">" characters. Do you have any idea about that.

Eg :

try.xml
<sample>lucene</sample>
‍‍‍

If I try with

@cm\:name:"try*" +TEXT:"lucene" ‍

@cm\:name:"try*" +TEXT:"<lucene>"‍

Both query is resulting me ""try.xml", since the text "lucene" is not inside tags. Why the search is behaving like this.? Any Idea?

Did you try directly with this code:

TEXT:<sample>lucene</sample>

Thanks,

No amita, I have a xml named try.xml and there it has the content <sample>lucene</sample>

I had written the query as

@cm\:name:"try*" +TEXT:"<lucene>"

I also tried with the query u added now, it too gives the same result amita.

Hi Jeya,

I am not getting what search result you want .
If you want to exclude use -
If you want to get the content with that text then use +

Clarify your requirement.

Thanks,

Let me explain you clearly amita.

I want to search the content of a file (ie., try.xml in my example) which is not an xml element. So from my above example, If I search by the text "sample", the search result should be '0'. So I want to exclude the text which is present inside the tags.

So I did a sample search query, just to test whether lucene is considering "<" abd ">" characters in its search or not. So i have written 2 queries

@cm\:name:"try*" +TEXT:"lucene"
@cm\:name:"try*" +TEXT:"<lucene>"

In which both the queries returned the same result. So from this we can say that lucene is not considering "<" and ">" in its search. I had an idea of writing query like this,


@cm\:name:"try*" -TEXT:"<*>"  +TEXT:"sample"‍‍

ie., eliminating the content which is inside the xml tags. But from the above conclusion those tags(<>) will not be considered.

So how could I pursue to eliminate the xml elements from searching?

Hi Jeya,

In this case you might have to check which Analyzer is using for search.
You can also create your own Analyzers . You need analyzer which will consider "< >" also during search.
