search using terms from lookup in an (mv) string field.

[drodman29]

I have an mvfield  of type string in my results. 

I want to search and match all values of this field for words that come from a csv lookup. 

LookupRows: 

{row1, "mary white"} 

{row2, "Tom White"} 

Results

Astring="Mary had a white lamb" , "tom had none" , "Joe was here" 

Astring="No match here" , "tom thumb" 

Searching with the lookup values against the full text of the event is not an acceptable answer.

Resolved using a _raw rename. 

BaseSearch | eval MyRaw=_raw | mvexpand Astring | eval _raw=Astring | search [|inputlookup searchterms.csv] | table _time, Astring
