Splunk Search

Alternative to Joins

I have 2 indexes say (A1 and A2) I have Fields a,b,c,d in index A1, In the index A2 I have fields b,e,f,g . I need to pull the data of the e,f,g fields from the A2 index if "b" values present in the both the index .I don't want to use the joins. Any way we can implement this ?.
Here is the sample search , what I have written but no luck ..
(index=A1 fields a,b,c,d) OR (index=A2 fields b,e,f,g)
| eval E=if(b==b,e,null())
| eval F=if(b==b,f,null())
| eval G=if(b==b,g,null())
| table E,F,G,b

Any help would be great ..Thanks 🙂

Can you please try this?
(index=A1) OR (index=A2) | stats values(a) as a values(c) as c values(d) as d values(e) as e values(f) as f values(g) as g by b | where ( isnotnul(e) OR isnotnul(f) OR isnotnul(g) )

Try like this. This will give results for values of field b which is present in both indexes

(index=A1) OR (index=A2)
| fields a,b,c,d,e,f,g
| stats values(a) as a values(c) as c values(d) as d values(e) as e values(f) as f values(g) as g dc(index) as indexes by b
| where indexes=2

try something like this:

(index=A1 a=* b=* c=* d=*) OR (index=A2 b=* e=* f=* g=*)
|stats values(e) as e values(f) as f values(g) as g by b

it will give you the values of e, f, and g for every b value

The stats command can replace join.

(index=A1 a=* b=* c=* d=*) OR (index=A2 b=* e=* f=* g=*) | stats values(c) as c values(d) as d values(e) as e values(f) as f values(g) as g by b | table e f g b
