Maybe, I misunderstood something in search mechanism in FHIR. But I have found a way if I have to find some objects which any value in some parameter.
For example, I wanted to build organization tree, in this case I have to know objects on a "first level" of this tree. And I think it should be an objects with empty partOf property. But documentation says nothing about it.
Or maybe there is another way how to achieve it?
Use the :missing modifier. (http://hl7.org/fhir/2016sep/search.html#modifiers)
E.g.
Organization?partof:missing=true

I have an extension where value[x] is sliced into valueCoding and valueDecimal.
I now would like to search on the code provided in the valueCoding and the value in valueDecimal.
Do I need to create two custom SearchParameters or is it possbile to define one, that allows a
request like the following?
http://localhost:4080/Patient?_customSearchParameter.code=ABC&_customSearchParameter.value=111
Thanks in advance!
Each search parameter must have a single search type. There isn't really a way to search a number in the same way you search a code, so you'll need distinct parameters. (You can see an example of how this was done for some of the Observation.value search parameters.)
I am implementing a CDS system, and I would like to use the DataRequirement type to ask for additional information. However, I am having some difficulties to understand the filter elements ("codeFilter" and "dateFilter").
For example, the property "path" of the filter elements is of string type, but what is the format to specify this path?
I have been searching some examples from the FHIR specification, and I've tried to follow the "path" in the resource object. I attach below an image with an example and the specification of the resource "MedicationRequest" that is being addressed in this example. Can anyone explain me over this example how to traverse throw the elements? What is the element "code" from the path refering to?
example DataRequirement.codeFilter
Can anyone help me with this issue? Examples of use would be appreciated!
Thanks in advance.
It's referring to the FHIRpath query - see spec.
The path element is a FHIRPath, but for simplicity, it assumes the ability to traverse references. Without that, the dereference would have to be explicit, as in:
medicationReference.resolve().code
The spec isn't clear on this, so I will submit a tracker to add that clarification.
Is it possible, using the AWS Ruby SDK (or just DynamoDB in general), to get an item or items from a table that uses a primary key only, and where that primary key ends with a certain string?
I haven't come across anything in the docs that explicitly answers this question, either in the ruby ddb docs or the general docs for ddb. I'm not saying the question is not answered, but if it is, I can't find it.
If it is possible, could someone provide an example for ruby or link to the docs where an example exists?
Although #Ryan is correct and this can be done with query, just bear in mind that you're doing a "full-table-scan" here. That might be OK for a one-time job but probably not the best practice for a routine task (and of course not as a part of your API calls).
If your use-case involves quickly finding objects based on their suffix in a specific field, consider extracting this suffix (assuming it's a fixed-size suffix) as another field and have a secondary index on that one. If you want to query arbitrary length suffixes, I would create a lookup table and update it with possible suffixes (or some of them, to save some calls, and then filter when querying).
It looks like you would want to use the Query method on the SDK to find the items your looking for. It seems that "EndsWith" is not available as a comparison operator in the SDK though. So you would need to use CONTAINS and then check your results locally.
This should lead to the best performance, letting DynamoDb do the initial heavy lifting and then further pruning the results once you receive them.

I have the following problem:
I want to avoid that one field of the copied row gets copied into the new row. (ME51n)
I thought that I could search somewhere in the debugger for this field name.
Example:
first row has the MATNR: 100-1-15
now i want to search in the debugger for the field MATNR. Is this possible?
(I know this example does not make sense, but my field is not used that often because it's an self-created field)
Or is there an user-exit especially for that?
Use watchpoints for that particular aim that you stated. In official documentation you can learn how to do it. The problem of finding suitable user-exit is not related to original question.
I Have two objects in same page but with different locations(tabs), I want to verify those objects each a part ...
i cant uniquely any of objects because the have same properties.
These objects clearly are unique to a point because they have completely different text, this means that you will be able to create an object to match only one of them. My suggestion would be to look for the object by using its text property, one of them will always have "Top Ranking" the other you wil need to turn into a regular expression for the text and will be something "Participants (\d+)".
I am assuming that this next answer is unlikely to be possible so saved it for after the answer you are likely to use but the best solution would of course be to get someone with access to give these elements ids for you to search for. This will in the long term be much easier for you to maintain and not using text will allow this test to run in any language.
Manaysah, do these objects have different indexes? Use the object spy and determine which index they have, the ordinal identifier index may be a solution to your problem. You could also try adding an innertext object property if possible, using a wildcard for the number inside the () as it appears dynamic.
try using xpath for the objects...xpath will definitely be different
