maybe there is a parameter in your browser that abort request when it is
too long to get an answer.

<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsLike
matchCase="false" wildCard="*" singleChar="."
escapeChar="!"><ogc:PropertyName>id</ogc:PropertyName><ogc:Literal>*13800000050414*</ogc:Literal></ogc:PropertyIsLike></ogc:Filter>
or better how it's used in my browser
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&VERSION=1.1.0&service=wfs&request=GetFeature&TYPENAME=IN.NUMERICIVICI.2012&Filter=%3Cogc:Filter%20xmlns:ogc=%22http://www.opengis.net/ogc%22%3E%3Cogc:PropertyIsLike%20matchCase=%22false%22%20wildCard=%22*%22%20singleChar=%22.%22%20escapeChar=%22!%22%3E%3Cogc:PropertyName%3Eid%3C/ogc:PropertyName%3E%3Cogc:Literal%3E*13800073301968*%3C/ogc:Literal%3E%3C/ogc:PropertyIsLike%3E%3C/ogc:Filter%3E

Your syntax are good. This is an old problem with int considered as string
Using ogc:PropertyIsLike works though, here is a request
<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsLike
matchCase="false" wildCard="*" singleChar="."
escapeChar="!"><ogc:PropertyName>id</ogc:PropertyName><ogc:Literal>*13800073301968*</ogc:Literal></ogc:PropertyIsLike></ogc:Filter>
Also this wfs support version= 1.1.0, you should do your request by
specifying this version

[mapserver-users] How to use filter encoding in MapServer in a WFS
query?
Hi all!
I need to query this WFS public service
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&service=wfs&request=getCapabilities
The layer I need to query is this one
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&service=wfs&version=1.0.0&request=DescribeFeatureType
It's a layer with a very big number of point features.
The OGC service is done using MapServer but I don't know the version.
I need to query this layer in a no spatial way: the simplest query I need
to do is something like this one
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&VERSION=1.0.0&service=wfs&request=GetFeature&TYPENAME=IN.NUMERICIVICI.2012&Filter=
<Filter><PropertyIsEqualTo><PropertyName>id</PropertyName><Literal>13800000050414</Literal></PropertyIsEqualTo></Filter>
My final query would like to combine several clauses using the AND logical
operator.
Unfortunately at the moment the simplest query above doesn't work: if you
try it in the response ther will be something like
HINT: No operator matches the given name and argument type(s). You might
need to add explicit type casts
I've done several attempts to change it and I've tried other queries: for
example
1) this one ...
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&VERSION=1.0.0&service=wfs&request=GetFeature&TYPENAME=IN.NUMERICIVICI.2012&Filter=%3Cogc:Filter%3E%3Cogc:PropertyIsEqualTo%3E%3Cogc:PropertyName%3Eid%3C/ogc:PropertyName%3E%3Cogc:Literal%3E%2713800000050414%27%3C/ogc:Literal%3E%3C/ogc:PropertyIsEqualTo%3E%3C/ogc:Filter%3E
returns
<gml:boundedBy><gml:null>missing</gml:null></gml:boundedBy>
so I think that in this case the sintax could be right but I'm not sure
and I don0't understand because the response is null
2) trying to do a spatial query like this one ...
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&VERSION=1.0.0&service=wfs&request=GetFeature&TYPENAME=IN.NUMERICIVICI.2012&Filter=%3CFilter%3E%3CBBOX%3E%3CPropertyName%3EName%3ENAME%3C/PropertyName%3E%3CBox%20srsName=%27EPSG:4326%27%3E%3Ccoordinates%3E7.626630,45.029061%207.673107,45.052713%3C/coordinates%3E%3C/Box%3E%3C/BBOX%3E%3C/Filter%3E
returns a right response.
I've found on the web that probably there is a workaround ...
http://osgeo-org.1560.x6.nabble.com/WFS-filter-creates-a-query-using-a-number-instead-of-text-td5130361.html#a5190402
that suggest to use the PropertyIsLike operator instead of the
PropertyIsEqual. I've tried to use it but it doesn't work in my case ...
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Numeri_Civici_2012.map&VERSION=1.0.0&service=wfs&request=GetFeature&TYPENAME=IN.NUMERICIVICI.2012&Filter=%3Cogc:Filter%3E%3Cogc:PropertyIsLike%3E%3Cogc:PropertyName%3Eid%3C/ogc:PropertyName%3E%3Cogc:Literal%3E%2713800000050414%27%3C/ogc:Literal%3E%3C/ogc:PropertyIsLike%3E%3C/ogc:Filter%3E
in this case after a long time it seems that the service goes in time out
and no data is returned ....
Now I am completely blocked .... :-(
Any suggestions / workaround?
Thank you very much in advance ...
