Hi Erick
Thank you for pointing out the sort behaviour of numbers in a string
field. I did not think of that. Will use float.
Would like to know how would you guys handle the usage of collection
alias in my case.
I have a 'product' collectionand Icreate a new collection'product_tmp'
for this field type change and index into it. I create an alias
'product' on this new 'product_tmp' collection.
IfI were to index to or delete documents from the 'product' collection,
SOLR will index on and delete from 'product_tmp' collection, am I right?
That means the 'product' collection cannot be usedanymore?
Even if I were to create an alias 'product_old' on 'product'
collection;issue a delete all documents or index on 'product_old', SOLR
will delete or index on 'product_tmp' collection instead?
My intention is to avoid having to updatethe clients serversto point to
'product_tmp' collection.

I'd go with float. Let's assume you want to sort by
this field. 1000000000.00 sorts before 9.0 if you
just use Strings. Plus floats are generally much more
compact.
bq: do I need to delete all documents in the index and do a full indexing
That's the way I'd do it. You can always index to a _new_ collection
(assuming SolrCloud) and use collection aliasing to switch your
search all at once
Best,
Erick

Hi
I have a field that is of "int" type currentlyand it's values are whole
numbers.
<field name="P_SupplierNeedinessIdx" type="int" indexed="true"
stored="true" multiValued="false"/>
Due tochange inbusiness requirement, this field will need to take in
decimal numbers as well.
This fieldis sorted onand filter by range (field:[ 1 to *]).
Should I change the field type to "float" or "string"?
For the change to take effect, do I need to delete all documents in the
index and do a full indexing? Or I can just do a full indexing without
theneed to delete all documents first?
