I have an effect that invokes below service call

    public getCandidates(): Observable {
        const url = 'Candidates Url';
        return this.http.get(url);
    }

I have an effect that invokes below service call

    public getMatchingCandidates(conditions: any): Observable
    {
        const url = 'Matched Candidates Url';
        return this.http.get(url);
    }

I have an effect that invokes below service call

    public getAssignedCandidates(id: number): Observable {
        const url = 'Assigned candidates url';
        return this.http.get(url);
    }

Candidate reducer :

    export const reducers = {
      search: fromSearch.reducer,
      candidates: fromCandidates.reducer,
      collection: fromCollection.reducer
    };

    Here is the injection of feature store to module

    StoreModule.forFeature('candidates', combineReducers(fromStore.reducers))
