Search in mdm

Question

Hi,
I want to perform search using field X where i need to exclude values 100,200,300.I do something like this :
FieldSearchDimension fieldSearchDimension =
               new FieldSearchDimension(
                    repository.getSchema()
                         .getField(Table,X)
                         .getId());
TextSearchConstraint textSearchConstraint2 =
          new TextSearchConstraint("100", TextSearchConstraint.EXCLUDES);
search.addSearchItem(fieldSearchDimension2, textSearchConstraint2);
This returns me records with values which are not 100 for X.How about other values?How do i add them to the search I cannot create too many objects for the same field.Please let me know.
Thanks,
Rekha

Answer 1

The memory exception comes if you do not close the objects and is picked up by your java garbage collector. Thus increasing the heap size.
Just adding to Jitesh's code
//you may want to see how many values you want to exclude, if there are too many values to exclude,
// possibility is you want to revisit your design. nevertheless.
String xvalues = {100,200,300,400}; //create the array of all the values to be excluded
FieldSearchDimension fieldSearchDimension =
new FieldSearchDimension(repository.getSchema().getField(Table,X).getId());
for(int i=0;i<xvalues.length;i++)
//constraint doesnt take the array so has to be for each element.
TextSearchConstraint textSearchConstraint2 =
new TextSearchConstraint(xvalues<i>, TextSearchConstraint.EXCLUDES);
search.addSearchItem(fieldSearchDimension2, textSearchConstraint2);
//add this line. this will set the object to null and hence will not be required to picked up by your garbage collector.
textSearchConstraint2 = null ;
or modifying above code a bit
//you may want to see how many values you want to exclude, if there are too many values to exclude,
// possibility is you want to revisit your design. nevertheless.
String xvalues = {100,200,300,400}; //create the array of all the values to be excluded
FieldSearchDimension fieldSearchDimension =
new FieldSearchDimension(repository.getSchema().getField(Table,X).getId());
TextSearchConstraint textSearchConstraint2 = null ;
for(int i=0;i<xvalues.length;i++)
textSearchConstraint2  = new TextSearchConstraint(xvalues<i>, TextSearchConstraint.EXCLUDES);
search.addSearchItem(fieldSearchDimension2, textSearchConstraint2);
textSearchConstraint2 = null ;
After returning the search constraint or after end of try catch,
close / nullify all the objects you instantiated other than the one you are returning.
