### Issue
Empty searchTerm search resolver
```
.orderBy(
`ts_rank_cd("${SEARCH_VECTOR_FIELD.name}", to_tsquery(:searchTerms))`,
'DESC',
)
.addOrderBy(
`ts_rank("${SEARCH_VECTOR_FIELD.name}", to_tsquery(:searchTermsOr))`,
'DESC',
)
```
builds the following SQL query:
```
ORDER BY
ts_rank_cd("searchVector", to_tsquery('')) DESC, ts_rank("searchVector", to_tsquery('')) DESC
```
I haven't been able to find doc on this issue, but after testing,
`ts_rank_cd("searchVector", to_tsquery(''))` slows down/freezes my local
db.
As well, ordering by ts_rank is useless without a searchTerm.
### Result
In local, with the imported 300k rows appEvent custom object,
'combinedSearchRecords' gql request with empty searchTerm reduces exec
time from 3s to 300ms.
