# Dely request and execute it after 2 seconds using lodash

This is the first step **Prepare redux store structure** of implementation smart proposal serch from this steps

1. Prepare redux store structure - https://github.com/daostack/alchemy/pull/2353
2. Create reducer for storing proposals in the redux store
3. Add browser cache to be able restore data from browser cache first
4. Save proposals list to redux store and subscribe redux store to graphQL endpoints instead of subscribing each separate component
5. Add lodash library to be able implement smart search by proposals using local storage first
6. Test everything

Review the linked, merged pull request #2353, which covers the first step of the proposal-search plan. The issue names Redux, browser cache, GraphQL endpoints, and lodash, but gives no files, tests, or entry point; clarify which step remains and what completion criteria apply before starting.
