+Sometimes `recsel` chokes on a large query, and you need to break the query into chunks with a pipe.
+
+This Kickstarter file has 374,853 records.
+Here's the chonky query:
+
+```sh
+recsel kick.rec -e "Category = 'Games'" -p "Subcategory,Avg(Goal)" -G Subcategory
+```
+
+It breaks down like this:
+
+| Chunk                         | Meaning                                       |
+|:-----------------------------:|:---------------------------------------------:|
+| `recsel kick.rec`             | Select records from `kick.rec`                |
+| `-e "Category = 'Games'"`     | Select only records where Category = 'Games'  |
+| `-p "Subcategory,Avg(Goal)"`  | Print the Subcategory and average goal        |
+| `-G "Subcategory"`            | Group by subcategory                          |
+
+Two ways to break the query apart:
+
+```sh
+recsel kick.rec -e "Category = 'Games'" | recsel -p "Subcategory,Avg(Goal)" -G "Subcategory"
+
+recsel kick.rec -e "Category = 'Games'" > games.rec
+recsel games.rec -p "Subcategory" -G "Subcategory"
+```
