Hi Jürgen,
you can use DM's fulltext search:
http://localhost:8080/core/topic?search=Kloppstockstr.&field=dm4.contacts.street
"search" is what you are looking for.
"field" is the type URI of the topics you want to search.
(The "field" parameter is optional. If not specified you'll search ALL topics,
regardless of type.)
The result is an array of topics. The array might be empty.
A topic is an object with 5 properties: "id", "uri", "type_uri", "value",
"childs".
"value" is the actual payload.
"childs" are the child topics of a composite topic. Note: these will be
included in the response only when you specify an additional parameter:
...&include_childs=true
Hint: when trying via curl you need to escape the & as \&
## Search Syntax (the "search" parameter) ##
When using several words (separated by spaces) the words are ORed by default.
That is
Klopstockstr. 20
matches a Street topic when it contains "Klopstockstr." OR "20"
To match it as a phrase (this is what you likely want) put it in quotes:
"Klopstockstr. 20"
IMPORTANT: in an URL you must encode characters like space and quote like this:
%22Klopstockstr.%2020%22
You can also use wildcards and other things. Actually you can use the entire
Lucene Query Syntax:
http://lucene.apache.org/core/3_5_0/queryparsersyntax.html
## DM Contacts hints ##
You can also search in composite topics like "dm4.contacts.person_name" or
"dm4.contacts.address".
DM concatenates the value of those composite topics as follows:
<First Name> <Last Name>
<Street> <Postal Code> <City> <Country>
So when you search for "Klopstockstr. 20 10557 Berlin" you'll find that exact
Address topic. (Don't forget to URL encode the spaces and quotes.)
IMPORTANT: you'll find topics as described here only if they are indexed with
mode "Fulltext Key". This is the case e.g. for all the types mentioned here,
also the composite ones like "Person Name" and "Address". However, this is NOT
the case for the "Person" type. So, at the moment you can't search for "Person"
topics by their name, but only for "Person Name" topics. But you can navigate
from a Person Name topic to a Person topic by an additional request.
You see a type's index mode(s) in the detail panel when selecting a type topic.
Tell me if you need further info.
Cool your Python script is growing :-)
Cheers,
Jörg
