| 17 | .SH DESCRIPTION
|
|---|
| 18 | .B xmg
|
|---|
| 19 | is an X interface to the
|

| 20 | .BR mg (1)
|
|---|
| 21 | information retrieval system.
|
|---|
| 22 | .PP
|
|---|
| 23 | Type a query in the ``Query'' box. The escape key clears the query text.
|
|---|
| 24 | .PP
|
|---|
| 25 | The first line or so of each matching document is listed.
|
|---|
| 26 | .PP
|
|---|
| 27 | Click on any line to show the complete document.
|
|---|
| 28 | .PP
|
|---|
| 29 | Shift-click to show the document in a new window.
|

| 30 | .PP
|

|
|---|
| 32 | .I Next
|

| 35 | to cycle through the list of documents (shift works here too).
|

| 36 | .PP
|

| 37 | If you change the query, existing windows continue to refer to the
|
|---|
| 38 | original query.
|
|---|
| 39 | .PP
|
|---|
| 40 | You can select either Boolean or ranked queries:

| 42 | .TP "\w'\fIBoolean queries:\fP'u+2n"
|
|---|
| 43 | .I "Boolean queries:"
|

|
|---|
| 45 | grouping.
|

| 46 | .TP
|
|---|
| 47 | .I "Ranked queries:"
|
|---|
| 48 | Documents are listed in order of relevance. A weight is shown
|
|---|
| 49 | alongside each. Weights are normalized to 100 for the most relevant
|
|---|
| 50 | document. Choose
|
