ROOT-198: remove default field from queries, make autocomplete wildcard* configurable

[jesconstantine]

This PR implements latest updates to palantirnet/solr-faceted-search-react#7 which makes the search app un-opinionated about main + autocomplete query default / query fields. This allows flexibility with the default search, autocomplete, and enables field boosting to be set in solr config.

Queries now have the following structure:

• main query: q=<mainQueryField.value> as opposed to q=tm_rendered_item:<mainQueryField.value>
• autocomplete query when autocomplete.appendWildcard is true: q=<mainQueryField.value>+<mainQueryField.value>*&df=mainQueryField.field
• autocomplete query when autocomplete.appendWildcard is false (default): q=<mainQueryField.value>

See the updates to the solr client repo tests for more details.

To accommodate these updates, this PR also updates the autocomplete config in the example config file.

To Test

Set up your drupals - if you're still set up from the last demo site PR, you should be good to go

1. Make sure you follow the steps in Fix mapped terms indexing federated-search-demo#20 to fix your index and ensure that federated terms are added to the index

Get your local app environment set up

1. Pull this branch down
2. Update the version of the search app dependency with yarn install

Add new autocomplete config

1. Observe updates to the src/env.local.js.example file
2. Add configuration to set autocomplete.appendWildcard to true, here is what
   mine looks like:

module.exports = {
  // REQUIRED: The default solr backend.
  // url: "https://ss826806-us-east-1-aws.measuredsearch.com:443/solr/master/select",
  url: "http://federated-search-demo.local:8983/solr/drupal8/select",
  // userpass: btoa("palantir:palantirqauser"),
  // OPTIONAL: The text to display when a search returns no results.
  // noResults: "Sorry, your search yielded no results.",
  // OPTIONAL: The text to display when the app loads with no search term.
  searchPrompt: "Please enter a search term.",
  // OPTIONAL: The number of search results to show per page.
  rows: 20,
  // OPTIONAL: The number of page buttons to show for pagination.
  paginationButtons: 5,
  // OPTIONAL: Machine name of those search fields whose facets/filter and current values should be hidden in UI.
  hiddenSearchFields: [
    // 'sm_site_name',
    // 'ss_federated_type',
    // 'ds_federated_date',
    // 'sm_federated_terms',
  ],
  // OPTIONAL: Provides config for adding autocomplete functionality to text search
  autocomplete: {
    url: 'http://federated-search-demo.local:8983/solr/drupal8/select',
    appendWildcard: true,
    suggestionRows: 5,
    numChars: 2,
    mode: 'result',
    result: {
      titleText: 'What are you interested in?',
      showDirectionsText: true,
    },
  }
};

Verify when autocomplete.appendWildcard = true a wildcard query is sent

1. Start the app with yarn start
2. The search app should load in a new browser window
3. Open your browser devTools (COMMAND + alt + i) for chrome / firefox
4. Click the Network tab of your devtools
5. Ensure that you aren't filtering any network requests by type, or at least ensure XHR is included in your filter
   • Chrome:
     
   • Firefox:
     
6. Refresh the page to start logging network traffic

Confirm: Single word/chunks are sent with chunk+chunk*

1. Type car into the search field
2. Observe there are 5 results returned
3. Click on the request for the autocomplete query request
4. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
5. Observe the query q param is car car*
6. Observe there is no default field param sent &df=
   

Confirm: Single world/chunks ending in a space are trimmed

1. Type car (note trailing space) into the search field
2. Observe the same 5 results are returned
3. Click on the request for the autocomplete query request
4. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
5. Observe the query q param is still car car*
6. Observe there is no default field param sent &df=
   

Confirm multiple word/chunks are sent with word1+chunk2+chunk2*

1. Type so m into the search field
2. Click on the request for the autocomplete query request
3. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
4. Observe the query q param is still so m m*
5. Observe there is no default field param sent &df=
   

Verify when autocomplete.appendWildcard is either false or not set, no wildcard is appended to the query

1. Type car into the search field
2. Observe there is only 1 result returned
3. Click on the request for the autocomplete query request
4. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
5. Observe the query q param is car
6. Observe there is no default field param sent &df=
   

Verify trailing spaces are still trimmed from the query

1. Type car (note the trailing space) into the search field
2. Observe there is only 1 result returned
3. Click on the request for the autocomplete query request
4. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
5. Observe the query q param is car
6. Observe there is no default field param sent &df=
   

Verify that when no autocomplete.suggestionRows value is set, it defaults to 5

1. Comment out the line setting autocomplete.suggestionRows in your env.local.js file
2. Set autocomplete.appendWildcard to true
3. When the app reloads, type car into the search field
4. Observe there are 5 results returned

Verify that the main search query no longer sets a default search field in the query: q=tm_rendered_item:<value>

1. Search for carrot
2. Click on the request for the search query request
3. Browse to the params / form data (if you can view source vs parsed it will be most helpful)
4. Observe the query q param is carrot and not tm_rendered_item:carrot

Works as designed.
