Legacy workspaces still hold the old stored expression, which omits
public.unaccent_immutable, so their tsvectors remain accented and can’t
match the new, unaccented queries. Metadata sync doesn’t touch
asExpression, so only a targeted drop/recreate fixes the underlying
column.
In simpler words, the search vector should contain `mader` instead of
`mäder` for the search to work properly. Therefore, this command
regenerates the search vector across every object that uses
`SEARCH_FIELDS_FOR_*`.
Note that dashboard has a searchVector, but breaks the pattern of using
`SEARCH_FIELDS_FOR_DASHBOARD`. If you look at
packages/twenty-server/src/modules/dashboard/standard-objects/dashboard.workspace-entity.ts:116,
the searchVector field is hard-coded as
```
asExpression: `to_tsvector('english', title)`
```
Therefore, the following code snippet.
```
const storedExpression = hasAsExpressionSetting(
searchVectorFieldMetadata.settings,
)
? searchVectorFieldMetadata.settings.asExpression
: undefined;
if (storedExpression) {
return storedExpression;
}
return undefined;
```
It checks whether the searchVector field already carries its own
asExpression value in metadata. If the settings object includes that
string, it returns it so the upgrade can reuse the existing expression
for objects that aren’t in our predefined lists. If not, it returns
undefined, signaling there’s no stored expression to fall back on.
