# Changes Made to Fix TypeScript Error

## Issue
TypeScript error in `src/brainyData.ts` at line 4339:
```
Object literal may only specify known properties, and 'searchField' does not exist in type '{ forceEmbed?: boolean | undefined; nounTypes?: string[] | undefined; includeVerbs?: boolean | undefined; searchMode?: "local" | "remote" | "combined" | undefined; searchVerbs?: boolean | undefined; verbTypes?: string[] | undefined; searchConnectedNouns?: boolean | undefined; verbDirection?: "outgoing" | ... 2 more ...'.
```

## Changes Made
1. Added the `searchField` property to the options parameter in the main `search` method
2. Added the `searchField` property to the options parameter in the `searchRemote` method
3. Added the `searchField` property to the options parameter in the `searchCombined` method

## Verification
- TypeScript type checking with `npx tsc --noEmit` completed without errors
- Build process with `npm run build` completed successfully without the previous error
- All tests passed with `npm test`, confirming that our changes didn't break existing functionality
