Phrase detection identifies phrases in your signals so that results with matching phrases can be boosted. This helps compensate for queries where phrases are not distinguished with quotation marks. For example, the query `ipad case` is rewritten as `“ipad case”~10^2`, meaning if `ipad` and `case` appear **within 10** terms (whitespace-delimited tokens) of each other, then boost the result by a factor of **2**.
This feature is deprecated in Fusion 5.9.15 and will be removed in a future release.
Lucidworks recommends migrating to [Neural Hybrid Search](/docs/5/fusion/hybrid-search/overview), which achieves superior relevance compared to legacy machine learning methods.
Phrases are applied in the [Text Tagger stage](/docs/5/fusion/reference/config-ref/pipeline-stages/query-stages/text-tagger-query-stage) of the query pipeline.
For more information about how to use phrase detection in the [Rules Editor](/docs/5/fusion/getting-data-out/query-enhancement/rules-editor), see:
* **Use Query Rewrites in the Rules Editor**
* **Use Phrase Detection**
This article describes how to use the Rewrites screen in the [Rules Editor](/docs/5/fusion/getting-data-out/query-enhancement/rules-editor).
## Query rewrite rule types
* **Head/Tail.** Replace underperforming queries with queries that produce higher click-through rates. Query improvements always require review before they are published. Schedule the Head/Tail Analysis job to get AI-generated query improvements based on your signals collection. \
\
Manually created Head/Tail rewrites must provide an "Improved Query" in a format appropriate to the type of request the rewrite will be applied to. For Legacy requests, this means a valid Solr query fit for use as the `q` parameter. For DSL requests this means a JSON string representing the main DSL query. \
\
For more information, see:
* [Underperforming Query Rewriting](/docs/5/fusion/getting-data-out/query-enhancement/underperforming-queries)
* [Head/Tail Analysis Jobs](/docs/5/fusion/reference/config-ref/jobs/head-tail-analysis)
* **Misspelling.** Fusion replaces misspelled query terms with their spelling corrections for better search results. Schedule the Token and Phrase Spell Correction job to get AI-generated spelling corrections based on your signals collection. For more information, see [Misspelling Detection](/docs/5/fusion/getting-data-out/query-enhancement/misspelling-detection).
* **Phrase.** Known phrases are boosted when they appear in new queries. Schedule the Phrase Extraction job to get AI-generated phrases based on your signals collection.
For more information, see [Phrase Detection](/docs/5/fusion/getting-data-out/query-enhancement/phrase-detection).
* **Synonym.** Synonyms are used to expand queries so that they include all known synonyms of the query terms. To retrieve AI-generated synonyms based on your signals collection, schedule the [Synonym Detection job](/docs/5/fusion/reference/config-ref/jobs/synonym-detection).
* **Remove Words** - Remove particular phrases from queries. Unlike other rewrites, these should be entered manually and are not generated by a job. For more information, see [Remove Words](/docs/5/fusion/getting-data-out/query-enhancement/remove-words).
## Facets
### Facet menu
To facet the rules list by **Status** or **Published**, click one of the facet items within the facet categories.
To facet the rules by **Confidence**, click and drag either slider to set the range of confidence you would like to see:
Faceting rules by confidence is not available for Head/Tail rewrites.

### Approve/deny rules
{/* // New or altered rules will need to be approved by a user with the appropriate permissions before the rule can be enabled. */}
1. Hold the pointer over a rule.
2. Select the checkbox that displays for that rule.
3. To modify multiple rules, hold the pointer over each rule and select its corresponding checkbox.
4. Click **Approve** or **Deny** as needed.
{/*
This is not an explicit option in the rewrite screen. Is this implicit by approval/denial?
### Enable/disable a rule
1. Hold the pointer over a rule.
2. Select the checkbox that displays for that rule.
3. To modify multiple rules, hold the pointer over each rule and select its corresponding checkbox.
4. Click **Enable** or **Disable** as needed.
*/}

2. Select the checkbox that displays for that rule.
3. To publish multiple rules, hold the pointer over each rule and select its corresponding checkbox.
4. Click **Publish Selected** to publish the selected rules.
#### Publish an individual rule
1. Hold the pointer over a rule.
2. Click the button.
3. To confirm, click **Publish**.
### Delete rules
#### Delete a single rule
1. Hold the pointer over a rule.
2. Click the trash can.
3. To confirm, click **Delete**.

### Sort rules
1. Hold the pointer over column titles. A icon displays for some titles to indicate the rules list can be sorted by that column.
2. Click the title column to sort the rules.
The column that is currently sorting the rules list is indicated by an or icon.
### Export rules
To export the rules list, click **Export**. This generates a `.csv` file that contains your rules.

4. Click **Save**. To exit without saving your changes, click **Cancel**.
The [Phrase Extraction job](/docs/5/fusion/reference/config-ref/jobs/phrase-extraction) automatically creates phrases based on your AI-generated data. When you navigate to **Relevance** > **Rules** > **Rewrite** and select the **Phrase** tab, the application displays the **Phrase Detection** screen.
When you manually add new phrases, subsequent job runs use those documents as input for machine learning to improve the job’s output. Unlike job-generated documents, manually-added query rewriting documents are never overwritten by new job output.
The course for **Query Analytics** focuses on how Fusion provides query analytics to detect and improve underperforming queries.
{/* // tag::review[] */}
## Reviewing auto-generated phrases
Phrases that are automatically generated by the [Phrase Extraction job](/docs/5/fusion/reference/config-ref/jobs/phrase-extraction) are assigned one of the following status values:
* **Auto**
These results have a confidence level as a threshold to automatically deploy them to the `_query_rewrite` collection. This threshold can be specified in the configuration parameter **Minimum Likelihood Score** (default value 0.1).
No action is required on these results, but you can edit them if you wish.
* **Pending**
The confidence level is ambiguous, and the result must be reviewed by a user before it can be deployed. It will only be moved from the `_query_rewrite_staging` collection to the `_query_rewrite` collection when its status has changed to "Approved" *and* it has been published.
### How to review a pending phrase result
1. Navigate to **Relevance** > **Rules** > **Rewrite**.
2. Select **Phrase** tab. The application displays the **Phrase Detection** screen.
Notice the **Status** facet on the left. Click **Pending** to view only the items that need review.
{/* // Currently this facet does not work (in the qrw-demo app). */}
3. Click the icon next to the phrase.
4. In the **Status** column, select either "Approved" or "Denied".
Optionally, you can also edit the phrase itself.
Although the Confidence field is also editable, changing its value makes no difference.
5. Click the **Close** icon next to the updated phrase:
Approving a phrase does not automatically deploy it to the `_query_rewrite` collection. When you have finished your review, you must click **Publish** to deploy your changes.
{/* // end::review[] */}
{/* // tag::add-new[] */}
## Adding new phrases
You can manually add phrases in addition to any generated by the [Phrase Extraction job](/docs/5/fusion/reference/config-ref/jobs/phrase-extraction).
### How to add a phrase
1. Navigate to **Relevance** > **Rules** > **Rewrite**.
2. Select **Phrase** tab. The application displays the **Phrase Detection** screen.
3. At the bottom of the rules list, click the icon. A new phrase appears at the top of the list.
4. Enter the phrase.
It is not necessary to set a confidence value.
5. Select the phrase’s status, depending on whether you want to deploy it the next time you publish your changes ("Approved") or save it for further review ("Pending").
6. Click the check mark to save the new phrase.
{/* // end::add-new[] */}
{/* // tag::publish[] */}
## Publishing your changes
### How to publish updated phrases
1. In the **Phrase Detection** screen, click the **PUBLISH** button.
Fusion prompts you to confirm that you want to publish your changes.
2. Click **PUBLISH**.
{/* // Currently this does not update the count of unpublished changes. */}
You can un-publish a query rewrite by changing its status to "denied", then clicking **PUBLISH**.
{/* // I am assuming this is the case. */}
{/* // end::publish[] */}
