React - How to redirect to another component on Search?

So I'm working on an app for school and I've been stuck on an issue for like two days. I'm building a search that gets data from TMDB, and all that works fine. When I type in the input all the data come flowing in! However, when I submit and try to redirect to the /results page which is linked to a component that displays the SearchResults when directed to, nothing happens and it stays on the homepage... I tried Redirect but either I'm using it incorrectly, or I shouldn't be using it in this case. Here's the code for my Search component, if you could help me out, I'd greatly appreciate it!:

import React, { Component, Redirect } from 'react';
import axios from 'axios';

class Search extends Component {
  state = {
    query: '',
    results: []
  };

  getInfo = () => {
    axios
      .get(
        `https://api.themoviedb.org/3/search/tv?api_key=6d9a91a4158b0a021d546ccd83d3f52e&language=en-US&query=${
          this.state.query
        }&page=1`
      )
      .then(({ data }) => {
        this.setState({
          results: data
        });
      });
  };

  handleInputChange = e => {
    e.preventDefault();
    this.setState(
      {
        query: this.search.value
      },
      () => {
        if (this.state.query && this.state.query.length > 1) {
          if (this.state.query.length % 2 === 0) {
            this.getInfo();
          }
        } else if (!this.state.query) {
        }
      }
    );
  };

  render() {
    return (
      <div>
        <form>
          <input
            className='search'
            placeholder='⌕'
            type='text'
            ref={input => (this.search = input)}
            onChange={this.handleInputChange}
          />
        </form>
        {this.state.results.length > 0 && (
          <Redirect
            to={{
              pathname: '/results',
              state: { results: this.state.results }
            }}
          />
        )}
      </div>
    );
  }
}

export default Search;

"Redirect" component is inside the "react-router-dom" package. use this approach:

import { Redirect } from "react-router-dom";
import React, { Component } from 'react';

class Search extends Component {
//...

render() {

    const { results } = this.state
    const { props } = this.props

    return (results.length > 0 ? <Redirect
        to={{
            pathname: "/results",
            state: {
                results: results,
                from: props.location
            }
        }}
    /> : <form>
            <input
                className='search'
                placeholder='⌕'
                type='text'
                ref={input => (this.search = input)}
                onChange={this.handleInputChange}
            />
        </form>
    )
}

}

You can use withRouter to get history prop injected and then do: history.push(“/results”)

The code will look something like this:

import React, { Component, Redirect } from 'react';
import axios from 'axios';
import { withRouter } from "react-router";

class Search extends Component {
  state = {
    query: '',
    results: []
  };

  componentDidUpdate(prevProps, prevState) {
  const { history } = this.props;
  if (prevState.results !== this.state.results) {
    history.push('/results');
  }
  }

  getInfo = () => {
    axios
      .get(
        `https://api.themoviedb.org/3/search/tv?api_key=6d9a91a4158b0a021d546ccd83d3f52e&language=en-US&query=${
          this.state.query
        }&page=1`
      )
      .then(({ data }) => {
        this.setState({
          results: data
        });
      });
  };

  handleInputChange = e => {
    e.preventDefault();
    this.setState(
      {
        query: this.search.value
      },
      () => {
        if (this.state.query && this.state.query.length > 1) {
          if (this.state.query.length % 2 === 0) {
            this.getInfo();
          }
        } else if (!this.state.query) {
        }
      }
    );
  };

  render() {
    return (
      <div>
        <form>
          <input
            className='search'
            placeholder='⌕'
            type='text'
            ref={input => (this.search = input)}
            onChange={this.handleInputChange}
          />
        </form>
      </div>
    );
  }
}

export default withRouter(Search);

This way you are programmatically navigating, using push method from react router's history.

Are you using React Router for routing?. Do you need to change your URL? There isn't much of a need for something like this. Sending someone to /results is just old school unless you are going to do something like /results?q=pulp&amp;piction so someone can refresh or link directly to the results.

For something like this just display your result component 

{this.state.results.length && (
  <SearchResults results={this.state.results} />
)}

If you are using a router and need to use the path for the school project school your teacher for dumb business requirements and give us more information about what you are using.
